Product Detail:
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 common color of diopside is blue-green to yellow-green, brown, yellow, purple, colorless to white. Luster for glass luster. If chromium is present in diopside, the mineral has a green tinge, so diopside gems are often confused with other gems such as yellow-green olivine, (green) tourmaline, and chrysoberite, which of course depend on other physical differences between the minerals to distinguish them.
Some diopside may also have cat’s eye; Such gems, such as quartz,...

Cordierite is a silicate mineral, usually light blue or light purple, glassy luster, transparent to translucent. Cordierite also has the characteristic of being remarkably polychromatic (tricolor), emitting light of different colors in different directions. Cordierite is usually cut into traditional shapes, and the most popular color is blue-purple.
Cordierite is similar in color to sapphire, so it is also called water sapphire. Nicknamed the poor man’s sapphire because ...

The distinguishing features of natural and Synthetic
Green sapphires cut dark blue protolith to show the multidirectional color of green or blue-green on the front, then natural green sapphires can be formed. yellow-green and Gray-green sapphires can also be found on the market, but their value is relatively low. Most of the properties of synthetic green sapphires are the same as those of natural products. The refractive index ranges from 1.76 to 1.77, and the refractive index...
