Because the quantity of rubies is relatively rare, the prices are relatively high. Generally, the cheapest ones are in the tens of thousands, and the slightly larger ones can reach hundreds of thousands.

For ordinary small shops, this high price is unbearable; Secondly, it is difficult to identify rubies, which can only be identified by professionals and equipment, and most shops do not have such personnel, so rubies cannot be recycled.

Matters needing attention in ruby maintenance

Ruby's chemical property is corundum, so ruby's necklace is also hard, but you can't touch other hard objects. If it collides violently, it will cause the gem to crack easily, but this kind of crack is invisible to our naked eyes.

In fact, the internal structure of the gem has been destroyed, resulting in dark cracks, which can be clearly seen with the help of a magnifying glass and microscope. After this collision, the gem left a flaw, which greatly reduced its appearance and value. So when doing heavy work and strenuous exercise, you must take off the ruby jewelry.
