What Is Black Kyanite?

Black Kyanite is a beautiful grey gemstone that has been used as an ornamental stone and in jewelry since ancient times. It holds great value in the eyes of enthusiasts and casual hobbyists alike.

Historically, it was thought to have magical powers and was used to ward off evil spirits and curses. Today, it’s still used in crystal healing and meditation practice because it’s said to help release negative energy and encourage good luck.

Black Kyanite symbolizes protection and healing for different cultures. Furthermore, crystal healers often use it because of its powerful connection to the root chakra.


Black Kyanite is a variety of the mineral Kyanite, a silicate of aluminum. It was named and discovered in 1789 by Abraham Gottlob Werner, who was studying rocks in Germany. 

The name Kyanite comes from the Greek word ‘kyanos’, which means blue. 

It was initially known as disthene because it has two different chemical compositions and properties. 


Black Kyanite is a rare, fibrous variety of Kyanite that forms long black threads. It is a stone with an appearance that can range from dull and flaky to shiny, glossy, and dark.

The stones are often found in fan shapes with elongated crystals and a waxy luster. They’re also sometimes found as massive formations polished into spheres or carved into beads.

In general, Kyanite is colorless or blue. Blue Kyanite is commonly found in small pieces, ranging from light blue to dark blue, sometimes even as purple or lavender.

Black Kyanite is one of the rarer forms of this gemstone. Its color varies from dark to light, depending on its purity and crystal structure. The more impurities present in the mineral (such as iron), the darker its color will be. It can range from almost pure black to brownish-black when it contains significant iron or manganese impurities.

Still, most specimens are pure enough to appear transparent or translucent with a slight blue-gray tint when light passes through them at certain angles. It forms in granular masses and has a vitreous luster. It also occurs as tiny crystals and as massive aggregates.

Physical Properties

Black Kyanite is an aluminum-rich silicate mineral that occurs in triclinic crystals. It has a Mohs hardness of about 4.5-7 and a specific gravity of 3.67-3.70. 

Black Kyanite is anisotropic, meaning it has different properties depending on which direction it’s cut from. When cut parallel to its c-axis (the longest dimension), it has a hardness of 4.5-5 on the Mohs scale and shows a brilliant luster with a vitreous luster. 

When cutting perpendicular to its c-axis, it has a hardness of 6-7 on the Mohs scale and shows a dull/waxy luster.

It is strongly piezoelectric and pyroelectric, meaning it can be used in the detection of sound waves and changes in temperature.

Black Kyanite is found in metamorphic rocks, as well as in igneous and sedimentary rocks. In addition, Kyanite is found in sedimentary rocks, pegmatites, and contact metamorphic zones. 

Pegmatites are coarse-grained, intrusive igneous rocks that form in magma chambers. They have a high water content and are usually found at the edges of tectonic plates.

        How Is It Formed?

        Black Kyanite crystal is formed in contact metamorphic zones. However, it can also originate from hydrothermal fluids and igneous rocks. The process starts when carbon dioxide, hydrogen, and oxygen react together to form methane. 

        The methane then reacts with water to form carbonic acid. The carbonic acid then reacts with silicate minerals to create an insoluble salt called Kyanite.

        This reaction can occur at different temperatures, depending on how much heat is in the environment. If there is little heat in the environment, Black Kyanite will develop slowly and steadily. 

        However, if there is a lot of heat in the environment, Black Kyanite will develop quickly.

        How To Tell If Black Kyanite Is Real?

        If you are questioning whether or not your Kyanite is real, it will help to do a scratch test. Kyanite has variable hardness (4.5-7), which can be tricky. One way to determine if your crystal is genuine is to scratch it with a coin.

        The Kyanite should scratch in places with a hardness of 4, but not in other areas. Imitation kyanite is usually made of glass and quartz. Both materials are too hard to be scratched by a coin at all.

        Another method is to look at the crystal’s cleavage. If it has perfect unidirectional cleavage, then it’s most likely real. Unidirectional cleavage means that the crystal has perfect cleavage in two directions.

        Finally, you can look at the price. Real black Kyanite costs more than synthetic versions because it’s rarer and harder to find. So if you’re looking at a piece that’s much cheaper than what you would expect, given its size, shape, and quality, then it may be false.

        Price & Value

        The price of Black Kyanite crystal can range from $20 to $100 per carat, depending on its quality and size. The larger the piece, the more expensive it will be.

        Luster: The most valuable Black Kyanites are those with a high luster, which means they sparkle when they catch the light. They also have a deeper, more intense color than other black gems.

        Cut: If you are looking for a particular shape, such as a cabochon or oval cut, you can expect to pay more than if you were looking for a small specimen.

        Color: Black Kyanite’s value will depend mainly on how dark the stone is and how many inclusions it contains. These can be bubbles or cracks within the crystal itself or foreign matter trapped inside when it was being formed during mining operations. Blue Kyanite is more valuable and sought after than black.

        Quality: The best crystals have high clarity ratings and are free from any imperfections, such as cracks or chips in the outer layer of the stone (which could cause them to break easily).
