Does jet shine through light?
Black jade is basically transparent, but it also depends on factors such as thickness and color. You can't buy completely opaque black jade. There are two kinds of jet, one is white jade bottom mixed with ink dots of different sizes, the other is sapphire bottom, and most of them can see uneven ink dots. Jet can transmit light, but the variety, texture, treatment and cutting methods of jet also affect its light transmission. After wearing jet for a long time, it may lose its luster due to the accumulation of sebum, oil sweat and other substances, and it needs regular cleaning and maintenance. In addition, prolonged exposure to light or the influence of chemicals may also lead to discoloration or damage of jet.
Will jet change if it is worn for a long time?
When jet is worn for a long time, it will be scattered. The specific process is that it will dry and turn white first, then the texture will become rougher and rougher, and finally it will turn green. Ink jade absorbs the oil and sweat secreted by human body during wearing, and its color will gradually turn green.
