Carbonado, also known as “black diamond,” is a rare and unusual type of diamond that is found exclusively in Brazil and Central Africa. Carbonado is often compared to other precious gemstones, including silicon carbide, due to its unique properties and composition. In this article, we will discuss how to distinguish carbonado and silicon carbide gemstones from other types of gemstones.
First and foremost, carbonado and silicon carbide gemstones have distinct physical properties that differentiate them from other types of gemstones. Carbonado is black and opaque, with a rough, pitted surface that resembles charcoal. Silicon carbide, on the other hand, can be found in a variety of colors, including green, blue, and purple, and has a smooth surface that can be polished to a high shine. Both carbonado and silicon carbide are much harder than other types of gemstones, including diamonds, and are capable of scratching or damaging them.
In addition to their physical properties, carbonado and silicon carbide gemstones have unique optical properties that distinguish them from other types of gemstones. Carbonado is known for its distinctive texture, which appears as a series of small, closely packed fractures that can be seen under magnification.black moissanite. This texture is caused by the presence of graphite and other impurities within the diamond crystal structure. Silicon carbide, on the other hand, has a high refractive index and exhibits strong birefringence, which causes it to display a colorful, rainbow-like effect when viewed under polarized light.
Another way to distinguish carbonado and silicon carbide gemstones from other types of gemstones is to examine their origins and geographic locations. Carbonado is found primarily in Brazil and Central Africa, where it is believed to have formed from a meteorite impact or other high-energy event. Silicon carbide, on the other hand, is a synthetic material that is created through a complex process of heating and cooling silicon and carbon atoms under high pressure. While natural silicon carbide does exist, it is extremely rare and found only in certain geological formations.
In conclusion, carbonado and silicon carbide gemstones are rare and unique types of gemstones that can be distinguished from other types of gemstones through their physical and optical properties, as well as their origins and geographic locations. By examining these factors, gemologists and collectors can accurately identify and appreciate the beauty and rarity of these special gemstones.
