Moonstone is a kind of feldspar, the most abundant mineral group in the crust of the Earth. Feldspar is mainly composed of silicates of aluminum with traces of other minerals such as sodium and calcium. When feldspar forms with potassium and attains a translucent, pearly form, it is known as a moonstone. The name of the moonstone comes from the similarity it has to the moon, and moonstones have been used in jewelry, especially for women, for centuries.
Several parts of the world, as well as Sri Lanka, have deposits of moonstone. Moonstone is classified as an orthoclase, meaning that it forms around volcanic and hydrothermal deposits, and has a translucent appearance, along with a sparkling luster. Moonstone is a type of orthoclase known as adularia, after the Adula Mountains of Switzerland, where the stone is abundantly circulated. Adularia crystallizes at a low temperature, and when it takes the appearance of an opalescent stone, it is classified as a moonstone.
When found in the rough, a moonstone is not an exciting sight. A skilled stone cutter must bring out the bright appearance of the stone, which must be cut with care. Normally, moonstones are cut in the form of a cabochon, a rounded and polished cut which lacks facets. The cabochon can take any form, though teardrop, round, and oval cabochons are all common. If cut properly, the stone will glitter and flow, exhibiting a property called adularescence, after the family of rock that moonstones come from.

Engagement rings and wedding rings are different both in look and symbolism. Usually engagement rings are worn prior to marriage to signify one's engaged status. The most general engagement rings are diamond solitaires, though engagement rings can be any color or choice of stone depending upon taste.
Like wedding rings, engagement rings to worn on the left hand ring finger. They are purchased alone, or they may be sold as part of a set. When the person is married, the wedding ring portion of the set is added and tends to be worn under the engagement ring on the ring finger of the left hand.
Wedding rings can also be sold individually from engagement rings and may be comparatively simple in design. Simple gold or platinum bands are still quite admired for both men and women. It's a good idea to choose from engagement rings that will fit with a wedding band, or alternately to get a set if the ring has any designs that might make it incompatible with a simple band.
Some wedding rings, especially in a set can also be quite complicated. They may include diamonds or other stones that set off engagement rings wonderfully. If engagement rings have peculiarities in shape and are not sold in a set, an alternative to purchasing a band that does not equal is having one designed to fit with the engagement ring.
In additional, often engagement rings and wedding rings that are designed to go together may be welded in the back to reduce friction of the rings rubbing together. Friction will eventually wear the rings down, particularly if they are 14 karat gold or higher. Most jewelry stores can achieve this simple operation a few days before a marriage takes place so women do not have to be without their engagement rings for long.
It is commonly customary for women to wear engagement rings. There are male engagement rings however these are less common. Usually both new husband and wife will wear wedding rings. Unlike engagement rings, wedding rings are generally not worn until after a marriage has taken place. While a diamond solitaire on the left ring finger may point out a lady's gagement, a simple band worn on the left hand ring finger by either a man or a woman signifies that the person is married.
