Quartz: An Array of Colors for Silver Jewelry Designs

Silver jewelry is highly agreeable and can accommodate almost any color gemstone of the rainbow. It is highly visible and present in gold jewelry, however, the colorless or whitish reflective quality of silver, creates a blank canvas onto which the multi colors of all the varieties of quartz can shine and dominate. These qualities of silver jewelry are most likely why quartz is a favorite choice of silversmiths, jewelry designers, and consumers, alike. The most common quartz varieties used for silver bracelets, silver rings, pendants, and earrings include the lilac and deep purple hues of amethyst, the bright and happy deep yellow of citrine, translucent light pink of rose quartz variety, the opaque, jet black type known as black onyx, and the clear colorless variety which is typically sold as quartz points.

Known as the birthstone for February, amethyst is said to aid in renewal and purification and is often associated with maintaining sobriety and assist with other types of addictions. Of the wide array of quartz varieties, amethyst is the most sought after, best known in association with silver jewelry, and cultivates the greatest intensity of pleasure and awe-inspriring interest. The origin of the term amethyst, come from the greek, "amethystos", literally meaning "not drunken". Jewelry designers and gem cutters typically fashion the amethyst in round, oval, and square shaped faceted gems, however, they can also be polished as a half round, domed, cabochon or used in a more rustic style which includes amethyst nuggets and amethyst points.


Of all the earth's minerals, quartz is the most abundant and is available in colors from clear and colorless to opaque and black. It is subdivided into two major categories based on individual crystal size with macrocrystalline the term used for varieties with crystals visible to the naked eye and cryptocrystalline or microccrystalline for those with crystals to small to be detected by the naked eye. Quartz is the byproduct of many different types of geological processes and is very common in granite, limestone, and sandstone and other types of rocks. A special variety known as cristobalite, is formed as the result of extremely high temperature and pressure from a meteoric impact.
