Due to the high market price of rubies, many people have come up with ways to improve the quality of gemstones. The market is full of fake ruby ​​products. How to identify rubies? Consumers need to understand before buying.
How to identify ruby:
Observing color: Due to the harsh natural growth environment, natural rubies tend to be less uniform in color, with a soft, linear ribbon distribution or a hexagonal growth zone inside. The synthetic ruby ​​color is extremely pure and has high saturation. The color is less natural.
Observing luster: Gemstones have several different lusters, while rubies generally have a glass luster or a strong glass luster. When we pick up a ruby, we can observe whether it is glass or strong glass luster, especially under the illumination of strong light, the color will become more vivid and bright, and the local or whole has a unique silky flash and luster. Quite strong.
Observing dichroism: natural rubies tend to have more obvious dichroism. The method of observing dichroism is also very simple. We take the gemstone up and observe the color in different directions of the gem. The ruby ​​can see the red-orange-red change. Other imitations do not have this characteristic.
Observing ruby ​​with cat's eye or starlight effect: The natural ruby ​​with special optical effect is a special ruby. When you observe it, you should observe its eyeliner or star line. The natural ruby ​​has its lines from the depth and the starlight is divergent. It is more irregular, with bright spots in the middle; and the synthetic ruby ​​has its lines floating on the surface, and the lines are clear and distinct. The star line is more regular, the position is centered, and there are bright spots in the middle.
Observing the cut: We generally observe that the high-quality natural red and sapphire processing is very careful, and it is carefully polished during the processing, and the curved surface is not polished; while the synthetic red and sapphire processing is generally processed during processing. Rough, visible polishing marks and chatter marks caused by rapid polishing - fire marks, the curved surface is often polished.
