GEMSTONE JEWELRY - One of the Unique Stones !

Primarily a collectors material and limited usage in jewelry making by its anisotropism and perfect cleavage. Kyanite'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.

GEMSTONE JEWELRY - More Turquoise !

To keep things short this time, here is a reuse of several earlier different types of gemstones and other materials.
.
This necklace set is an inline string of stablizied Sleeping Beauty Turquoise from Arizona with small Mother of Pearl rounds and highlighting crystals. A silver plated hook clasp is attached. French Hook earrings with the stabilized Turquoise and crystals complete the set.
.
Stabilized turquoise - Turquoise that is soft or normally referred to as "chalk" Turquoise is infused with a clear epoxy resin. This resin, under pressure, is absorbed into the rock, which permanently hardens the rock and deepens the color. Unlike the collectible natural Turquoise which deepens in color over time by gradually absorbing oils from the skin as it is worn, the colors in stabilized Turquoise are permanent. Most of the Turquoise on the market today is stabilized and should not cost as much as natural Turquoise. Stabilized turquoise can be very beautiful, and is a good buy. Because of it's hardness and consistant color, stabilized Turquoise wears much better in Jewelry.
