Rubies and emeralds, golden water bodhi sapphire, tourmaline, etc. belong to the genus of colored gems. Transparency: refers to the extent to which a gemstone allows visible light to pass through. In the naked eye identification of rubies, the transparency is generally divided into five levels: transparent, translucent, translucent, sub-transparent, and opaque. 1. Transparent It allows most of the light to pass through, and when you look at the objects behind it through the gemstone, you can see clear outlines and details. 2. Subtransparent It can allow more light to pass through. When observing the object behind it through the gemstone, the outline of the object can be seen, but the details are blurred. 3. translucent It can allow part of the light to pass through. When observing the object behind it through the gemstone, only the outline shadow of the object can be seen, and the details are not visible. 4. Sub-transparent Only a small amount of light can pass through the edges of the gemstones, but the objects behind them cannot be seen through the gemstones. 5. opaque Basically, light is not allowed to pass through, and light is totally absorbed or reflected by the object.
