yanite's importance is due to being one of the index minerals that are used to estimate the temperature, depth, and pressure at which a rocks undergoes metamorphism. With care, Kyanite can be faceted into a beautiful blue gemstone. Lapidarists have found it to be an interesting material when cut and polished. .This particular design incorporates two styles of Kyanite that has been cut and polished. First are enlongated barrels of a dark blue variety and the second style is light blue rondel shaped beads. These Kyanite beads are paired with Mother of Pearl (MOP) round polished beads and silver-plated balls with a toggle style clasp. Matching French Hook earrings complete the set.

Kyanite is one of three minerals to have the same chemical composition . These are Kyanite, Andalusite, and Sillimanite. Kyanite is the high pressure polymorph, Sillimanite is formed at high temperature, and Andalusite is the low pressure polymorph. Occasionally, clear and very colorful blue Kyanite is encountered. This material is highly prized by those who cut gemstones. It can be cut as a cabochon, faceted, or used to produce beads and pendants. Kyanite is considered to be an "exotic" gemstone because it is not often used in jewelry.

Mother of pearl, also called nacre, is an iridescent layer of material which forms the shell lining of many mollusks. Pearl oysters and abalone are both sources of mother of pearl, which is widely used as an inlay in jewelry, furniture, and musical instruments. Mother of pearl comes in several natural colors, and is often bleached and dyed for decorative use. The dye retains the shimmering layers which make mother of pearl so sought after. Depending on the shell the Mother of Pearl is taken from, it may be processed into large flat or curved pieces, small pieces sometimes call nuggets or processed as polished beads. Two substances actually combine to create mother of pearl. 
The first is plates of aragonite, a material which is secreted by the mollusk. Aragonite contains calcium carbonate and conchiolin, a natural protein. Alone, the plates are very hard, but also very brittle. As a result, the organism also secretes an organic material similar to silk to layer between the plates. The result is a strong, flexible material which can withstand hard use. .
