Chromium corundum is a very precious gemstone, its color is very bright, usually red or pink. The color of chromium corundum comes from the chromium element in it. This gemstone has a very high hardness and can reach 9.0, which is harder than steel. The chemical formula of chromium corundum is Al2O3, which is a crystal of alumina with very high corrosion resistance and wear resistance.
Chrome corundum was first discovered in the late 19th century, when it was considered a red sapphire. Later, it was found that chrome corundum and sapphire have different chemical compositions, so it was named chrome corundum separately. Chrome corundum is mainly produced in East Africa, Sri Lanka, Thailand and Australia, among which the most famous origin is Ulumi in Tanzania.
The color of chrome corundum is very bright, this is because the chromium element in it can absorb other wavelengths of light and only reflect red or pink light. The brighter the color of chrome corundum, the higher the value. In addition, the hardness of chrome corundum is very high, it can be used to make jewelry, watch dials and industrial knives, etc. The corrosion resistance and wear resistance of chrome corundum are also very good, so it is widely used in chemical industry, metallurgy and machinery manufacturing and other fields.

The brighter the color and the better the quality, the higher the price of chrome corundum.
