People who are interested in gems may find a "strange thing". There are some pinks on the mall, and sapphire will be written on the orange jewel label. Some small partners can't help but say that the boss is when we are color blind? Actually, today, Xiaobian tells you why pink gems are called sapphire?
Both Sapphire and Ruby are corundum minerals with a Mohs hardness of 9. It is the hardest natural mineral on earth except diamonds. The basic chemical composition is alumina. Not all corundum minerals are gemstones. Only translucent or transparent and colorful corundum can be called gemstones.
The red and chrome-containing corundum is red, which is the ruby ​​we know. But the concept of sapphire is different. Except for the red corundum gemstones, all other tones of corundum are collectively called sapphire. The blue sapphire is due to the traces of titanium and iron. In addition, corundum with different elements will appear in different colors, such as champagne, yellow, pink, orange, orange and purple, etc., known as Sapphire.
A long time ago, in the early stages of mining, corundum gemstones were only red and blue. It is called ruby ​​sapphire directly. Later, with the development of technology, it was discovered that more and more different colors of corundum gemstones were created. Finally, the agreement reached by the experts is: the red corundum gemstone is ruby, the blue corundum gemstone is sapphire, and the other color of the corundum gemstone is colored sapphire.
Therefore, if you see a pink jewel in the market and a sapphire on the label, don't doubt your eyes, and don't feel that the business is ignoring us. Because it is indeed a sapphire.
