Among the four recognized precious gems, namely diamonds, yoqut, safirlar, va zumraddlar, apart from the high cost of synthetic diamonds, which have not been officially sold in large quantities, the other three gems can not only be manufactured in large quantities, but also have production costs. It is much lower than natural products and has been officially sold on the market. One of the earliest successful production is ruby.

Kabi erta 1877, French chemist Frémy produced artificial rubies, but the particles were small and the cost was high. Ichida 1902, the French scientist Werner Leaf produced artificial rubies by flame melting. Bir necha yil o'tgach, ichida 1910, artificial sapphires were produced in the same way.

As the technology was not mature and popular at that time, artificial rubies and artificial sapphires were not common in the market. It was not until after the Second World War, bu, in the late 1940s, that artificial rubies and artificial sapphires were commonly sold in the market. Not only were the prices quite expensive, but the sellers often did not say that they were artificial, bu, they were often mixed with natural Sold in the product. It can be seen that the rubies of that period are not necessarily natural, because artifacts have been sold as early as that time.

After the 1950s, due to the popularization of production technology, the prices of artificial rubies and artificial sapphires plummeted. By the end of the 20th century, the price of artificial rubies had fallen to a few tenths or even one percent of natural rubies. The price of artificial sapphire is also much lower than that of natural sapphire. Materikda Xitoy, from the 1950s to the end of the 20th century, some people in the gem industry called artificial ruby ​​”Rubin stone”, which is actually the transliteration of the English word “Yoqut”.

Since the prices of artificial rubies and artificial sapphires are much lower than natural products, how to identify them has become an important task. Afsuski, it is impossible for ordinary consumers to identify them by themselves. If you want to accurately identify them, you can only ask a gem expert or find an appraisal agency.
