Strontium boroaluminate synthetic gem, commonly known as "luminous jade", is a new man-made product invented in China. It has a long afterglow time, is an environment-friendly luminescent material, and is also a new multifunctional health care ornament. Although before this, people used to call it "luminous jade" or "luminous gem", it is called "artificial strontium boroaluminate" because it must be named after the main components in artificial gem's chemical formula in accordance with international practice when applying for national standards, and because it is artificially synthesized by high technology, the word "artificial" must be added before the name, so it is called "artificial strontium boroaluminate" gem.

Fluorite is also called fluorite, fluorite powder and fluorite powder. [1] is an equiaxed mineral, and its main component is calcium fluoride (CaF2). Fluorite is an alkaline diluent, named after it emits the same fluorescence as fireflies under the irradiation of ultraviolet rays or cathode rays. But when fluorite contains some rare earth elements, it will emit phosphorescence. That is to say, fluorite can still emit light for a long time after leaving ultraviolet or cathode ray irradiation. The output of this phosphorescent fluorite accounts for a small proportion. In fact, most of the luminous pearls are made of fluorite. Because fluorite crystals are generally large, fluorite night pearls can be found in very large volumes.
