As an internationally recognized precious gemstone, rubies, sapphires, emeralds, gold emeralds and diamonds are among the world's five rare gems. However, in China, the popularity of rubies and sapphires is far less than that of diamonds. Although prices have risen sharply in recent years, the pace of price increases cannot keep up with the “steps†of jade, tourmaline and diamonds. Especially the sapphire with a large head, the price is only 1/3 of the same quality ruby, the price is very high. Many people think that sapphire is blue. Why are some orange and pink gems also called sapphire? Sapphire is a generic term for corundum gemstones of all colors except red. Therefore, the color of sapphire can be not only blue, but also yellow, green, orange, brown or even colorless. For a long time, whether the pink corundum belongs to ruby ​​or sapphire has been controversial internationally. I personally think that pink corundum is too bad if it is classified into the ruby ​​category, because the biggest value of ruby ​​is its color, and the red color of pink corundum is not rich. If it is classified as ruby, the price will definitely be greatly affected. The pink corundum on the market is basically also referred to as "pink sapphire".
