silver rings manufacturers What are the criteria for evaluating the pros and cons of Star Red and Sapphire?

Опубликовано в от Король

(1) The starlight should be obvious, the position should be centered, and there should be no missing rays.

(2) The starlight is clear, which makes people feel that it comes from the inside of the gemstone, rather than floating on the surface of the curved (ie egg noodle) драгоценный камень.

Because the natural starlight red and sapphire are loved by everyone, they are very charming, but they are expensive and difficult to obtain. As a result, synthetic star red and sapphire came into being. В 1947, the American Linde Company first synthesized Starlight Red and Sapphire successfully. В 1949, it began to dump on the market. Because its price is much lower than the natural Starlight Red and Sapphire and the starlight effect is obvious, it is welcomed by people. The basic method is: heating at 1500°C for 2 часы, then cooling to 1 100° C., staying for 72 часы, so that rutile has sufficient time to precipitate along the parallel directions of each two sides of the hexagonal column, forming a starlight effect After processing the corundum with reasonable technology, you can get the red and sapphire ring with six stars. my country has already produced artificially synthesized six-shot starlight red and sapphire in batches, and they have been sold in the market and jewelry fairs.

Anyone who has never touched gems thinks that gems are mysterious. Фактически, most people do have many rubies around them. That is the so-called diamonds called “17 бриллианты” или “21 бриллианты” in our watches. It should be pointed out: Except for a very small number of precious watches that use natural diamonds as the dial and strap decorations, a large number of ordinary watches use hard and wear-resistant artificial rubies as bearings (there is a bearing on the top and bottom of each axis), so When we open the back cover of the watch, we can see two of the artificial rubies shining red.
