However, there is a kind of gem, and pigs seem to bear the name of "the worst".
I won't play games with you. It's spinel.
First introduce the following spinel, a gem.
The chemical composition of spinel is magnesium aluminum oxide, with equiaxed crystal system and refractive index of1.712 ~1.730. It is a single refractive gem, and the refractive index of different colors is different. It has a moderate deviation of 0.020. On the basis of good cutting, spinel can show stronger fire color than ruby and sapphire. The color system of spinel is very rich, and red spinel is the most famous.
Spinel ores are found in Myanmar, Vietnam, Tanzania, Madagascar, Sri Lanka and Tajikistan. Generally speaking, the value of spinel minerals in Myanmar and Tajikistan is higher than that in Madagascar.
Why is spinel the saddest gem?
First, it has been mistaken for ruby in history.
The two most famous spinels in history are "Timur Ruby" and "Black Prince Edward Ruby".
The former, weighing 36 1ct, is crimson, probably originated in Afghanistan, and has been known as the "world tribute" of the East since 16 12.
This spinel is called "Black Prince Edward Ruby" and weighs about 1.70 carats. It is produced in Myanmar and set in a prominent position in front of Britain and Wang Guanzhong. Experts estimate that this famous red spinel is worth about $550,000.
In ancient China, most of the rubies in the top-wearing Hualing worn by many officials and ministers were spinel.
Ah, it really looks like a ruby if you don't look carefully. . . )
Second, it is mistaken that spinel is not a precious gem because of its large output.
The output of top-grade spinel is not much, and it is as rare as top-grade ruby. Because the exploitation of spinel is not as clear as that of ruby and sapphire, there are few mines specializing in the exploitation of spinel, and most of them are obtained by accident when mining ruby and sapphire. Spinel is often accompanied by ruby and sapphire, which is why it is often mistaken for ruby in history.
Moreover, spinel covers the color gamut that ruby can't cover, such as HOTPINK and other colors. Its beautiful color and superior price make it stand out in the colorful world. In recent years, the popularity of spinel can be clearly felt in marketing departments at home and abroad.
Third, many people think that only red spinel is expensive to look good.
It is true that red spinel with large particles and beautiful color is extremely rare and precious. The discovery of Mahenger spinel in Tanzania has also changed people's market awareness of spinel, and the pink and flame spinel produced here is deeply loved by people. The pink spinel at the top has a very bright neon luster and is called "Jedi Knight". However, in addition to the red series of spinel, other colors of spinel have gradually entered the field of vision of mass consumers and gradually been recognized by collectors and famous jewelry brands. For example, Dior, Champion Paris, Chow Tai Fook and so on.

Today's spinel is not the kind of gem that plays with body double. It has been widely recognized by the international jewelry industry, and many European collectors realized this earlier than China collectors. Spinel has high hardness, few cracks, few impurities and rich colors. Its own advantages make it reasonable to double the value of spinel in recent years, and the price increase is only to make up for the undervalued value in the past. Compared with the auction data in recent two years, the price of red spinel in Xiaoke has increased by more than 1 times, but it is about 5 carats. Spinel conquered many princes and nobles in ancient and modern times and at home and abroad with its brilliance. Spinel that is good enough should never be a substitute for anyone. Piggy also believes that he will always shine in the jewelry market.
