Ruby [1] , which means corundum of a red color, is a type of corundum and consists primarily of aluminum oxide (AL 2O 3) . The red color comes from chromium (CR) , mainly Cr2O3, the content is generally 0.1 ~ 3% , the highest is 4% . Containing Fe, Ti and blue said Sapphire, non-chromium CR color of other colors of corundum also collectively known as Sapphire.
Most natural rubies come from Asia (Burma, Thailand, Sri Lanka, Pakistan, China Xinjiang, China Yunnan, etc.) , Africa...

Black SPINEL, from it comes out, the output is self-evident, how many hundreds of millions, most of these will not be done by hand inlaid finished products, generally using wax inlaid technology to solve the inlaid, black spinel electroplating equipment requirements are higher, in general, the aging of some equipment or the improper treatment temperature of skilled workers will cause the coloration of black spinel caused by electroplating. We hope that the vast number of jewel...

Amethyst is a tripartite crystal system, the crystal is hexagonal columnar, the cylindrical surface is transverse, there are left shape and right shape, twin-crystal is very common. The hardness is 7. The crystal often contains irregular or winged gas-liquid inclusions. It is one of the most expensive members of the crystal family, because the water crystal contains Mn, Fe3+ and appears purple. Transparent, with obvious polychromatism observed under dichromatic mirror.
The ame...

The difference between Garnet and similar gem and synthetic garnet. Gemstones similar in colour to various garnets, including rubies, sapphires, artificial corundum, topaz, emeralds, Jadeite, etc. , are heterogeneous and can be distinguished by polarisation. It can be distinguished in density, inclusion, refractive index, dispersion and fluorescence. The difference between Garnet and Synthetic Green Garnet is mainly due to the internal inclusions and density. The synthesized G...

Citrine varies in color from yellow to light brown and is easily confused with citrine. The yellow color in citrine is due to the presence of iron oxide in water. Natural citrine is scarce and produced in few places, with only Brazil and Madagascar producing high-quality Citrine in limited quantities. Amethyst and nicotinite are often heated to make them change color and look like citrine, or even fake citrine. Citrine has complete joints, citrine has no joints, and the lowest...
