First of all, it must be made clear that Moissanite diamonds and diamonds are two different things. Moissanite diamonds are not diamonds or synthetic diamonds. The reason why they are compared is that they are too similar.
Composition and formation:
Diamonds are divided into natural diamonds and artificial diamonds. One is natural gemstones formed by the precipitation of carbon under unique high temperatures and pressure. The other is artificially cultivated quickly by imitating the formation environment of diamonds. Their main elements All are carbon, while Moissanite is synthetic silicon carbide.
Natural diamonds and man-made diamonds:
Whether natural diamonds, man-made diamonds, or Moissanite, it is difficult for ordinary people to distinguish between the bare stones used for jewelry after polishing.
In terms of usage:
The price of natural diamonds is high, the output is low, and the price is not high for industrial use, so they have been used for jewelry settings for many years. Part of artificial diamonds are used in industrial fields, such as cutting tools, and part of them are used to replace natural diamond jewelry inlays. Moissanite has been used in electronics for many years, such as light-emitting diode materials. With the continuous improvement of people's technology of synthesizing Moissanite, Moissanite became known and inlaid as jewelry. Moissanite is also a kind of artificial gemstone very close to diamond in terms of various physical properties. These three things are infinitely close in appearance, but there are essential differences after all.
Moissanite is not a product of recent years. Moissanite is also divided into natural and artificial Moissanite.
What is the difference between Moissanite and diamond? How to distinguish?
》A diamond of the same quality has a different fire color from Moissanite. The diamond is a radial cold light, and the firelight is a refracted warm light. The fire of Mozambique is more than 2.5 times that of diamonds. You can see the difference between the two by directing white light on the stone.
Mozambique's fire is more brilliant than diamonds.》The constituent elements are different. Diamond is carbon, and Moissanite is silicon carbide. Is this impossible to distinguish from the surface or with a drilled pen?
Both diamonds and Mossan can pass the drill pen.》The hardness of a diamond is different; the hardness of a diamond is 10. Moissanite is about 9.25. The glass can also be cut, and the stone is not damaged. Although the hardness is high, both are afraid of violent falls and impacts.
》The density is different. When measured with diiodomethane (density 3.32 g/cm3) liquid, the Moissanite floats up and the diamond sinks. If the Moissanite is cut according to the standard size of one carat of the diamond, the actual weight will be less than 1 carat.
》The index of refraction is different. When viewed with a 10x magnifying glass, the cut line of the diamond is transparent and clear without ghosting. Moissanite will have weak ghosting.
》The inclusions are different. The diamonds' inclusions under the magnifying glass are mostly cloud-shaped or point-shaped, rarely needle-shaped. The inclusions of Moissanite are mostly columnar and flaky.
》 fire, the diamond is burned in pure oxygen, it will be directly sublimated without impurities, and the Moissanite will have burning matter.
