Calcite, which gets its name from "chalix" the Greek word for lime, is a most amazing and yet, one of the most common minerals on the face of the Earth, comprising about 4% by weight of the Earth's crust and is formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. Some of these rock types are composed of better than 99% calcite. Why would a collector be interested in such a common mineral? Because of its extraordinary diversity and beauty! The jewelry industry has become facinated with its beauty and many colors in all shades of the rainbow.

Jade on todays market is primarily composed of Nephrite; Jadeite Jade has become quite rare and in its emerald-green, translucent form is referred to as Imperial Jade or "gem jade". A small amount of cromium in Jadeite accounts for the color of Imperial Jade. Other color-based names for Jadeite Jade are Yunan Jade, for a uniquely appearing dark green, semitranslucent Jade, Apple Jade for apple (yellowish green) green Jade, and Moss-in-Snow for white Jade with vivid green spots and streaks. Nephrite and Jadeite Jade ranges in color from a somewhat greasy-appearing, white to dark and light shades of green, gray, blue-green, lavender, yellow, orange, brown, reddish-brown, and black. An important dark green variety of Nephrite is sometimes known as "spinach Jade". The chromophore in all Nephrite Jades is usually iron. Nephrite jade is usually opaque to translucent in thinner pieces. This particular Jade used in this piece is a shade of yellow. The name Jade has been, and continues to be, applied to a variety of materials that superficially or closely resemble Jade but are not composed of either Jadeite or Nephrite. So as the old saying gos "Buyer Beware !".

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 organic material similar to silk to layer between the plates. The result is a strong, flexible material which can withstand hard use.
