Classification of crystals

◆ Crystal:

The most representative, versatile, versatile and helpful gem is called the "King of Crystals". It has the functions of storing memory and assisting concentration, and is the synthesis of all energy. Large crystal clusters themselves are endless, which can purify the negative energy around them. Eliminating electrical radiation is commonly known as "suffocating". The essence of crystal is colorless and transparent, but it gives people a white feeling. What is the reason?

The whiteness of crystal is related to its internal structure and light scattering and recombination on the surface. Crystal structure is an ice crystal state, which is the purest natural form of silica condensation. However, the internal structure of the crystal is very complicated. When a beam of light strikes its surface, a series of transmission, reflection and refraction will occur. Crystal is a combination of countless tiny particles. When external light shines on the crystal surface, tiny surfaces in all directions will transmit, refract and reflect the light, thus forming a layered scattered light. In the world of light, ordinary white light is a mixture of seven visible colors in proportion. When natural light shines on the crystal, it will produce transmission, reflection and refraction in all directions of the particle assembly. When scattered light recombines and meets our eyes, our visual sense crystal is white.

◆ Citroen:

As the birthstone of November, the Lord prefers fortune, which often brings unexpected wealth. For people who rush about, this kind of gem can calm their mood and eliminate fatigue. Topaz is the general name of golden yellow, orange yellow, brown yellow and light yellow crystals, and is often called "crystal topaz" or "topaz crystal". In French, topaz means lemon, which probably means that the color of this crystal is close to lemon. The ancient Roman philosopher Pliny once praised topaz with "gold" and "precious stones". The color of topaz is mainly caused by iron or chromium in the crystal. Topaz is better than those bright and flawless, and orange is more popular.

◆ Amethyst (Amethyst)

It is the birthstone of February, representing a pure and harmonious state of mind. You can put it under the pillow when you sleep, which can stimulate your thinking and sleep peacefully. Exposure to amethyst can improve spirituality and increase wisdom. Putting amethyst clusters will make people feel happy, have no desire and so on. In short, it has magical power. The ancients thought it could ward off evil spirits, protect the body, bring happiness and longevity, detoxify and avoid harm, just like an amulet. Amethyst is regarded as the "stone of honesty" by westerners, which symbolizes sincerity, integrity and kindness, as well as innocence and happiness, and is suitable for the underage generation. Purple is regarded as a noble color by people, accompanied by mysterious legends, so the nobles in court and religious circles are proud of owning amethyst, which is a kind of enjoyment and a kind of wealth. Amethyst became an eye-catching symbol at the coronation ceremony in England. In the eyes of westerners, amethyst can sublimate love, represent friendship, calm emotions, stimulate thinking, improve relationships, be safe and auspicious, and attract money to ward off evil spirits. According to the western explanation, the energy of amethyst is restrained, and all the crystal clusters grow towards the center, which shows that it has great cohesion. Placing amethyst on the bed or anywhere in the home can change the human magnetic field, strengthen life and bring good luck to the owner. Amethyst was once a precious variety among precious stones because of its rarity. Since the discovery of amethyst in Brazil in the18th century, the jewelry market has changed due to its abundant reserves, and the price of amethyst has dropped sharply, which is why it is called "semi-precious stone" by the business community. However, gem-grade crystals with bright colors and flawless transparency, as well as jewelry amethyst gems weighing tens of carats, are still loved. The most valuable purples to purples are Ural Amethyst and Siberian Amethyst. The name originally refers to the place of origin, but because it is used all over the world, it actually refers to the quality, not limited to the place of origin. High-quality amethyst is processed into facets for inlaid jewelry or collection; Slightly ground into plain surface or polished into beads, inlaid or perforated to make necklaces and bracelets. Scraps carved into handicrafts are not discarded, and exquisite bonsai is made to make the best use of it. Amethyst is found in many places in the world, but it is rarely mined and supplied to processors in batches. The main producing areas are Brazil, Uruguay, Zambia, Australia, Madagascar, the former Soviet Union, the United States, North Korea, India, Mexico, Japan, Iran, South Africa and Sri Lanka. Brazil's amethyst mine is second to none in the world. The famous producing area is located in the southern region. At the beginning of the 20th century, an amethyst cluster weighing 350 tons was dug up. Amethyst in China is mainly distributed in Jiangsu, Yunnan, Xinjiang, Qinghai, Shanxi, Inner Mongolia and other provinces, but amethyst is lighter in color and less in quantity. In domestic jewelry and jade shops, many old craftsmen know that the amethyst in Wutai Mountain is good, which is characterized by its large volume, strong color and light pit.

◆ Shi Ying related.

The energy representing fortitude, decisiveness, courage and perseverance can help the authoritative energy gem.

◆ Tiger Eye Stone

Can inspire people's courage, bring self-confidence, for those who are not strong and decisive. Wearing this gem will remind you to keep positive and enterprising confidence at all times. It is one of the varieties of crystal, with colors ranging from brownish yellow to brownish red, blue and red, and transparent to translucent. Structurally speaking, this is an interesting mineral, because it is a real crocidolite illusion, that is, the oriented mineral fiber bluestone quilt is completely replaced in time, but the original fiber shape has not been disturbed. When the object is cut into flat thick plates for the first time, this fiber combination is like a silk pad; However, if it is cut into an oval non-convex shape and at right angles to the fiber layer, a satisfactory cat's eye effect will appear. Skilled cutting can occasionally produce well-defined "eyes", but common tiger's eye stones have asbestos-like fiber ripples and several groups of opal bands appear. Crocidolite and petrified wood are sometimes called by this name wrongly.

◆ Tea crystal or smoke Shi Ying.

Represents fortitude, tenacity, restraint, faith and easy cause. Smoke crystal is one of the most attractive members of the crystal family, referred to as smoke crystal for short. It is a crystal variety with smoky gray, smoky yellow, yellowish brown and brown. Smoke crystal is the best product with uniform color, no cotton and bright and clean. Some people think that the beautiful color of this gem is caused by radioactive radium in the rocks around the primary deposit. In fact, in the surrounding rocks seen in the Swiss Alps, the radioactive content varies with height. This change leads to different colors or tones of smoke crystals in this area. According to this inconsistent view, experts can find the desired crystal and its variants with greater confidence. In the experiment, white crystals can indeed get smoke crystals by radioactive irradiation. Smoke crystal originated in Scotland, and it is widely used to decorate colorful national costumes, becoming a de facto "national stone". Although for gemologists, interest in history and tradition is only one of the producing areas, in fact, there are more smoke crystals in other areas than in Scotland. Smoke crystal deposits in the United States, Switzerland, Ceylon and Spain are well known to the world, especially Maine, New Hampshire and Colorado. Brown and smoky yellow in smoke crystals are called tea crystals. Its color is like smoke flowing in the air. Its color is caused by radioactive substances. According to the research of Herba 1979, it is considered that when aluminum is contained in the solution instead of silicon, the colorless crystal can be turned into brown crystal by irradiation with No.60 drill. Almost all brown glasses and accessories on the market are products with radiation discoloration. A long time ago, although some places produced smoke crystals, they could not be used. "Hunan Tongzhi" said: "Yong Sui crystal stone, occasionally tea crystal Cai Pu, the natives should not use it, so it is not surprising."

◆ Moss crystal green ghost

Triangular green fog shadow or moss-like crystal: it has the ability to gather wealth. Natural green crystal is rare because it is brilliant and rare. At present, there are several places where green crystals are found in China, among which Donghai County in Jiangsu Province is the most abundant, followed by Yunnan and Xishan in Beijing. The crystal shape of the green water in the East China Sea is perfect, accompanied by crystal clusters. The smallest single crystal is 2 cm× 1 cm× 1 cm, and the largest is 5.5 cm× 45 cm× 8 cm, with uniform color and good transparency, and most of them are short columns. The formation of its green tone is related to the ferrous ions contained. Green crystal was called green crystal in ancient times. "Natural History" contains: "Its youth is as white as the moon, and its beauty (beauty) is lovely"; "Seven Repairs" said: "Japan has a sapphire crystal".

◆ Rose Shi Ying

Its warm color can promote emotional development, help to pursue love, grasp love and enjoy the gem of love, and help people communicate with each other.

◆ Quartz cat's eye

From the colorful rings of soap bubbles in the sun to the hazy moonlight-like halo, all belong to optical effects. These optical effects are embodied in jewelry, adding a bit of mystery to magnificent gems, and opal is an example. Quartz cat's eye is a kind of opal. When Chinese and foreign mineralogists talk about water field, they always mention it. Quartz cat's eye has many common names, such as cat's eye and cat's eye. Chinese jewelry circles call it Lezishi, also known as Oriental Cat's Eye or Sri Lankan Cat's Eye. Its oldest name is "Lion Bear", which means it was carried by a lion. In the East, opals, such as quartz cat's eyes, are regarded as a symbol of good luck. It is believed that it can protect the owner's health and avoid danger. With it, there will be a bright future. Where does the charm of quartz cat's eye come from? Originally, it contains fibrous, tubular and needle-like inclusions. When these inclusions are arranged parallel to the crystal direction of the gem, if they are cut into a convex shape so that the inclusions are parallel to the bottom surface, when the light shines on the gem, these inclusions will have a concentrated emission effect on the light. At this time, people can see a bright band of light in the gem, which we call living light. If you rotate the gem, the living light will flash, similar to the cat's eyes. With the shaking of the gem or changing the illumination angle, the light can move flexibly or open and close freely, from wide to narrow or from one bright band to two or three and then combine into a bright band, emitting unpredictable light of wisdom from the gem, full of vitality and aura, just like a cat's eyes in the dark. This strange optical phenomenon is called cat's eye effect. Besides quartz cat's eye, there are other gems with cat's eye effect, such as aquamarine cat's eye, tourmaline cat's eye, actinolite cat's eye, diopside cat's eye, square column cat's eye and so on. Among them, the golden green cat's eye is the most precious, and only this gem can be called cat's eye. In order to distinguish it from other gems with cat's eye effect, the name of the mineral should be added in front of the cat's eye. Quartz cat's eye has many colors, from white to taupe, yellow-green, black or light olive green to dark olive green, but the most common color is gray. In the quartz cat's eye, there can also be some high-grade varieties, with narrow cat's eye lines and yellowish brown background, which can be as beautiful as opal. However, its preciousness is far less than that of Opal, and the price gap is also very large. Quartz cat's eye can be matched with gold and platinum, and the jewelry made is not only noble and elegant, but also has a unique flavor. All kinds of earrings made of it are suitable for wearing at night. In the crystal clear, it reveals dazzling brilliance, sometimes hazy and sometimes dazzling, which will add a charm to you against the background of the lights. Necklace made of quartz cat's eye, matched with dresses of various corresponding colors, is chic and generous, the color is not monotonous, and it does not lose everyone's demeanor. When appreciating a ring inlaid with quartz cat's eyes, you can hold the ring in your hand and turn it in the sun to observe the changes of the cat's eyes. Eyeliner is straight and bright, bright in color, and can reflect a few rays of light around the "eyes", which is the best product.

◆ Water gallbladder crystal

Shen Kuo, a scientist in the Northern Song Dynasty, collected a story about Meng Qian Bitan in his life, in which he told an anecdote: "The scholar Song Shu's family had a pearl as big as an egg, which was slightly swollen and clear as water. When you hold it in your hand and look at it in the sun, the end will be a little green and the color will fade. When I turn around, the green place always falls. I don't know what it is, it's called Didi Cui. " According to experts' research, "Didi Cuizhu" is water gall crystal. Purple is dark blue, reddish and purplish. Judging from this, Didi Cuizhu may be amethyst. The Song people's meticulously written "The Story of Clouds Passing through Eyes" recorded in detail the rare treasures he saw in his life, including a passage: "Ye Sen's old crystal hook is hollow and gurgled, with a leaf in it, which fell with the water." This thing is also a water gallbladder crystal. Water gall crystal, named after containing water droplets similar to animal gallbladder. The crystal in the Ming Che blends with the clear water drops, so it is really difficult to tell who is the crystal and who is the water by static observation. Smart sellers often show water bags to customers dynamically. A strange stone collector bought bipolar water bladder crystals at the booth. He described it like this in his pen: The master was fascinated by me and took out two timid chicken hearts from the "multi-treasure chest". He held the first one in his hand, shook it a few times and handed it to me. I saw a drop of water inside, as big as mustard seed, hovering in the crystal; He handed me the second one without shaking. The water drops in the chicken's heart are as big as soybeans. When the gesture is slightly tilted, the water will drift with the tide. Water crystal is a beautiful gift, colorful and cherished. Experts from Jiangsu Institute of Geology and Mineral Exploration bought a magical "rainbow stone" from Donghai Crystal Market. This strange crystal stone is light brown and transparent, and its appearance is 18, which is the size of an egg. Crystals contain gas, liquid and solid inclusions. When rotating the strange stone, the small round bubbles on the two water tanks in the crystal will fluctuate with the water. If it's amazing to find water bladder in rainbow, it's even harder to find colored water bladder in crystal. There is a crystal collector in Donghai county, who collects a strange kind of crystal, named "Red Water and Dragon Ball". The crystal of the wave is wrapped in red, green and yellow bile, which has three bodies: solid, liquid and gas, and the viewers are all amazed. Another collector found a crystal the size of a ping-pong ball with six water sacs in it. He was named "Six Thieves" and bought at a high price. Have you ever heard of a glowing water sac? Yes, more than 80 years ago, a villager in Danba, Sichuan got a water gall crystal. There are some green things floating in the water, which will glow at night, so it is called the "night pearl". Unfortunately, the owner didn't know the treasure, so he smashed it out of curiosity, and the water leaked out, so the green things didn't shine. Crystal water bags are very expensive. An exhibit in geological museum, China, contains a fist-sized water sac crystal with a diameter of about 3 cm. An expert from Hebei Geological Bureau revealed that he found a crystal with a diameter of 5cm in 198 1. But being king is slow. A gemstone collector in Hunan collected a water sac crystal with a width of 5.7 cm, a height of 6.2 cm and a thickness of 3 cm. The water sac is about 4 cm in diameter. * * * There are three cavities, which are separated, so water can still gurgle. This crystal is pure and transparent, and its six sides are semi-circular cone-shaped, which is intact, and its diameter is larger than the national collection of crystal water capsules 1 cm. From this point of view, it is the largest water capsule crystal in China at present. Interestingly, Brazilians found that the composition of water droplets wrapped in crystals is very similar to that of magma water, and indigenous people regard it as "virgin water". According to legend, people can live longer by drinking it. Strange, how can there be courage in the crystal? Geologists have made it clear from its shape: unlike the common hexagonal prism crystal, the water capsule crystal is a hexagonal bipyramid, a short cylinder with long cones at both ends. It is a kind of high-temperature crystal (β-strain), the formation temperature is above 579℃, and it occurs in the cracks between sandstone and graphite granite in the vein, so the crystal has two conical tops. Generally, the crystal size is only 1 ~ 5cm, and the formed silicon dioxide is in short supply and malnutrition, and there are gaps in the crystal, which contain water, gas or other particles. The size of bubbles in inclusions varies from a few millimeters to 3 centimeters, and the liquid accounts for about half of the total volume of bubbles. "One bottle is dissatisfied, and half a bottle hangs in the air". It's interesting to shake it gently and the water drops are on and off. Graphite particles often float on the water, jumping up and down when shaking, like flying mosquitoes, becoming an obvious symbol. Water gall crystal is a treasure on earth. When you have it, you must cherish it!

◆ Barasuishou

The color of peach blossom stone is deep red, and the color of hibiscus stone is light red. It has a hibiscus color, from pink to rose, and then to rose, so it has the reputation of rose crystal. Because of its pink color, people also call it pink season. In a word, this is an unusual mineral gem with charming color. Barasuishou, I have never heard of a fairly large single crystal with no obvious and definite external shape. Generally, it is a brittle fracture with no obvious impurities mixed in, which is famous for its single color. Usually, the slightly transparent white extends to the inside in a straight line, which divides the large blocks unevenly. This is called the "white arrow path". The white arrow path is thick and thin, just like the extension of ribs. When the crystal contains rutile fiber inclusions, after it is cut into a cambered shape, there will be six radial starlight, which is extremely beautiful and turns into an ornament, showing a jewel-like appearance. Unfortunately, most of Barasuishou's transparency is poor and there are many cracks. After sun exposure, the color gradually fades with the passage of time, and the hardness is 7 degrees lower than Mohs. So it is often used for carving into handicrafts. Brightly colored ones are ground into beads and strung together with stones of other colors to make jewelry. If it is made into bonsai, fruit boxes, spheres and small animals, it is also very popular. Shi Shuo said: "The colorless crystal on the market is dyed with medicinal juice, so it is called Taohuashi". At present, for low-quality materials, dip dyeing is sometimes used to make them produce deeper tones or make them uniform. Dyed gems usually show unnatural tones and fade faster than the real colors. Barasuishou is produced in granite pegmatite, and its main producing areas are Indian, Japanese, American and Namibian. High quality crystals come from Brazil and Madagascar. Although there are many mines in China, few are of high quality, mainly in Inner Mongolia and Hebei. The color of Barasuishou is different from the place of origin. This kind of crystal produced in Fujian is really rare and strange in color. According to the textual research of Shoushan Stone, Barasuishou was born in the land of the moon and the sea, and his quality is moist and greasy, which is slightly inferior to that of white crystal. The first color is white, and the second color is white and snow white. Again, white and slightly green; There are also light yellow ones, but the output is small. Yes, lard white is the best. This is not credible. When the hibiscus flower was first picked, it was white, which was out of harmony with every stone. Touch it with your hand, the air is eroded, and the color becomes lard white. However, the essence is distorted, and encore is wrong? According to legend, during the Qianlong period, "a general sent someone to take it and put it into the wooden frame, which was much better, so the general cave was the top priority." "This cave is also named after it. It is very old, soaked in rain, and it is difficult to find the collapsed place, so it has become a rare treasure.

◆ Rainbow Crystal

This is a crystal with tiny bubbles or liquid filling cracks, which produces a rainbow by interfering with light. Cracks can occur naturally, or they can be caused by artificial heating and sudden cooling. A rare crystal rainbow stone was found in Donghai County, which contains gaseous, liquid and solid inclusions. And white, irregular surfaces. From a certain angle, there is a rainbow surface, which is 2 cm long and 0.6 cm wide to 1.2 cm. The surface is composed of three continuous colored rainbows, showing more than 20 colored bands, which is beautiful. Interestingly, Napoleon's wife Josephine has a dazzling gem collection, which is made of rainbow crystals.

Crystal is a huge and distinctive family. In addition to the crystal members mentioned above, there are alum crystals such as alum, amethyst as bright as grapes, topaz as bright as cabbages, etc. It is hard to imagine that there is such a stunner in the world! Why are the colors of crystals in nature so different? Looking through this colorful crystal world comes from different coloring mechanisms, which are caused by different "coloring ions" and "coloring centers" in the jargon of experts. The coloring of amethyst is generally considered to be caused by iron-containing hydroxide; On the other hand, Barasuishou is considered to be colored by chromium impurities, and manganese and titanium elements are also colored. If there is aluminum in the composition instead of silicon, the crystal is yellow. All smoky crystals often contain a lot of carbon, and there is also a saying of "free silicon". The reason why crystal stone has color is not only related to the color center, but also related to its external factors, that is, it must have the influence of radiation, otherwise even if it has a colored center, it will be difficult to shine. Through the exploration of rock crystal's coloring mechanism, people have developed a method of artificially changing the color and coloring the crystal, which makes the already colorful crystal family dominate again.

About the magical obsidian

Obsidian may be all monochrome, stripes or spots. The most famous obsidian is rainbow obsidian with flashing rainbow, and some items are oval, forming so-called monocular obsidian or binocular obsidian. However, from the price point of view, rainbow monocular obsidian and rainbow binocular obsidian are the most expensive, because in addition to the relatively scarce output, the appearance is also quite beautiful.

Because of the pure energy of obsidian, it belongs to energy absorption. In other words, it is generally recommended that Obsidian wear his right hand. Almost all the crystals are left-handed, except Obsidian, because according to the ancient Qi method in China, it is generally the principle of left entry and right exit. So the left hand is intake and the right hand is exhaust. Wearing obsidian in the right hand helps to absorb its negative energy, including unclean things.

Obsidian, because of its powerful and pure energy, can be placed in a heavy place in Sha Qi, or even made into an obsidian Buddha statue, which has a superior effect of avoiding evil spirits. But please note that obsidian itself can mainly absorb a lot of negative energy, but it will not be removed, so it must be purified within a certain period of time.

Rainbow obsidian has an energy magnetic field that gathers rainbow light, in other words, it plays a considerable role in the realization of things and wishes. In addition, rainbow obsidian is also one of the best gems for Buddhist practice. For home, placing obsidian is also the best guardian stone for town houses to ward off evil spirits.

Because obsidian itself is the most attractive gem among all spar, obsidian was used as an exorcism tool or even a treasure in ancient China and even in the west. In addition, because obsidian corresponds to the undersea wheel, it is quite useful for stability and peace, even for people who are sick or insomnia. Wearing obsidian helps to improve.
