Identification of Ruby One
Among the many red gems, only rubies and red spinels show red-dark red fluorescence under long-wave ultraviolet light, and the luminous ones may be rubies or spinels. Rubies are heterogeneous, and spinels are homogeneous. Under normal circumstances, the mass body can only be detected with a simple polarizer. The former is rotated 360 degrees between the orthogonal polarizers and appears four times of extinction and four times of brightness, and the latter is full extinction.
Identification of Ruby 2
Once again, the shape of the ruby is also an important way to distinguish. The faceted type composed of many small planes on the surface of ruby is more expensive than the curved type with smooth surface. Navíc, pay attention to the thickness of the gemstone. If it is too thin, the light will leak out from the quilt, and it does not appear to flicker; if it is too thick, it will appear bulky.
Ruby identification three
When we buy ruby rings, we must observe the cutting of rubies. The processing of high-quality rubies is very strict, and every link needs strict control. Proto, the ruby rings we see are not only very delicate in texture, And the workmanship is very fine, the overall gloss of the ruby is also very good. Však, because of the low price of synthetic rubies, there are no strict procedures in the processing process, which also makes synthetic rubies look rougher.
