It is often marveled that professional jewellery appraisers can see the variety of gems at a glance. After thinking about it for a while, it is not a must, but can only secretly sigh the jewels "water is too deep." In fact, most of the time, people in the gem industry use the luster of gemstones to help judge the gemstone species. What is gloss? for example! Diamond gloss The unique luster of diamonds means that the light reflects a strong light on the surface of the gemstone, which is extremely strong in the crystal gemstone. The reason why we can see at a glance the difference between diamonds and glass and crystal imitations is the diamond luster of diamonds. Agilent gloss For example, crystal gems such as red sapphire, zircon, and garnet will show the brightness behind diamonds. Sometimes because the gem itself has a color, it is more intense. Glass luster Most of the crystal gemstones, as well as some jade, are such lusters, such as tourmaline, topaz, crystal, emerald, jade, etc., like the reflective feeling of glass. The better the cut of the gemstone, the finer the polishing, the stronger the gloss. Grease gloss It belongs to the typical luster of Hetian jade. The surface of the jade has a greasy feel and is very moisturizing. The high-quality Hetian Baiyu is like a piece of fat oil. The white peony is greasy and has a high value. Waxy luster Some organic gemstones and jade show such a luster. For example, coral, beeswax, turquoise, etc. It is a kind of reflective feeling like paraffin. It is not like the luster of glass, nor the greasy feeling of grease. It is somewhere in between. Pearl luster This is the unique luster of pearls that distinguishes pearls from other imitations. It is due to the continuous reflection of light from the surface of the pearl and the near-surface crystalline layer. This fine structure can sometimes cause a colorful color, such as the malachite green of black pearls. Some of the resin luster is yellow-yellow-brown gemstone, and a gloss similar to that of resin such as rosin can be seen on the cross section. Such as amber. Resin luster on rosin When the silky glossy transparent gemstone is a fibrous aggregate, the surface has a bright, silky luster, which is called silky luster. Such as fibrous wood stone, tiger eye stone.
