The reason why mozambas are cheap is because they are synthetic gems and can be mass-produced. Mozambas are gems with the closest physical characteristics to natural diamonds. Their appearance is very similar to diamonds, and their fire color is better than diamonds, and their hardness is second only to diamonds. However, in diiodomethane liquid, mozambas will float up and diamonds will sink.
Mozambican diamonds are not equal to diamonds. Diamonds are carbon atoms, while Mozambican diamonds are synthetic silicon carbide and are man-made products. Because they can be synthesized artificially, the output of Mozambican diamonds is relatively large, which leads to the fact that the price is not expensive and can be used as a substitute for diamonds.
Mozambican diamonds are also called moissanite and carbon silica. Their appearance is similar to that of diamonds, and they are a kind of gem with the closest physical characteristics to natural diamonds. Because diamonds are single refractive, Mozambican diamonds are birefringent, and the dispersion is higher than diamonds, so the fire color of Mozambican diamonds is better than diamonds.
As we all know, diamonds are the hardest gems in nature, and their hardness has reached the full level of 10. The hardness of mozambas is second only to diamonds, and the Mohs hardness is 9.25. Using diiodomethane liquid measurement, mozambas and diamonds can be distinguished. Diamonds will sink, while mozambas will float.
