Radiant and intense, this variety of kyanite has caught the attention of gem lovers with its striking teal color.
Best known for its dark blue color, kyanite derives its name from the Greek word kuanos, meaning deep blue. Teal Kyanite, as its name suggests, instead possesses a vibrant teal hue, making this a desirable gem for its saturation of color. Not many other colored gemstones can match this color saturation, with only the teal topaz, Alexandrite, and high-quality aquamarine having similar visual properties.
Though similar to those gems, Teal Kyanite stands out due to some features unique to this stone. Kyanite frequently displays instances of color zoning, with areas of lighter to darker saturation displayed within a single gemstone. It also often shows instances of streaking or blotching in white. Due to these qualities, it is extremely rare to find gem-quality specimens that are over two carats in size after being cut.
Kyanite is most well known for being an anisotropic gem. This means that the hardness of the stone can vary depending upon how it is cut. A long axis cut will result in the hardness being on the lower end of the scale, measuring from 4 to 4.5 on the Mohs scale. Cutting it perpendicular to the axis will result in the hardness measuring higher, ranging from 6 to 7.

• Kyanite is also believed to boost one's capacity for concentration and self-expression.
• In ancient times, kyanite was thought to follow the magnetic fields of the Earth, and that suspending this stone from a thread would cause it to function as a compass needle.
• Kyanite can be worn for deep meditation, working best when placed on the throat chakra.
