Amethyst

A purple or violet form of transparent quartz used as a gemstone. Also a purple variety of corundum used as a gemstone.

Amethyst is rare in the deep colors that characterize fine quality. It is usually colored unevenly and is often heated slightly in an effort to distribute the color more evenly. Heating at higher temperatures usually changes it to yellow or brown (rarely green), and further heating removes all color. It contains a little more iron oxide (Fe₂O₃) than any other variety of quartz, and its colour probably arises from this iron content. Heating removes the colour or changes it to the yellow of citrine; most commercial citrine is made in this manner.

Notable deposits are found in Brazil, Uruguay, Ontario, and North Carolina. The birthstone for February, amethyst is usually faceted with step cuts or emerald cuts but also has been used since ancient times for carved intaglios. The Indian variety is the most precious. When made into drinking cups or bound on the navel, it was claimed to prevent drunkenness. It was also believed to sharpen the wit, turn away evil thoughts, and give a knowledge of the future in dreams. Drunk in a potion, it was thought to expel poison and render the barren fruitful. More recent work has shown that amethyst's coloration is due to ferric iron impurities. Further study has shown a complex interplay of iron and aluminium is responsible for the color.

Traditionally included in the cardinal, or most valuable, gemstones (along with diamond, sapphire, ruby, and emerald), amethyst has lost much of its value due to the discovery of extensive deposits in locations such as Brazil.

Amethyst can be used to in attractive pendants, necklaces, rings, ear studs and bracelets. Amethyst stones are usually set in gold and silver jewelry. Amethyst jewelry can be combined with pearls, Swarovski crystals or zircons. Amethyst earrings can be worn frequently since the gemstone is fairly durable. Combine amethyst with emeralds or pearls for stunning jewelry styles.

Although cutting is the most basic enhancement method necessary to display the beauty of a gemstone, there are many fascinating methods by which man has demonstrated his ability to draw maximum color, luster, clarity and brilliance from natures earthbound treasures. A basic understanding of these enhancement techniques will add to your appreciation of the beauty, durability and value of the gemstone jewelry you already own, or plan to purchase in the future. The darker colors of amethyst are rarely enhanced to perfect their color.

Care of Amethyst:

If worn regularly, amethyst earrings and rings tend to lose their brilliance due to a layer of oil and dirt. It is essential to clean amethyst jewelry carefully so as to protect its luster. Amethyst jewelry can be cleaned with warm soapy water and a soft brush. Use a soft cloth to wipe it dry. Do not wear amethyst jewelry while exercising, swimming or doing housework. Amethyst jewelry must not be subjected to extremes of temperature or vibration. Do not use an ultrasonic cleaner on amethyst. Avoid sudden temperature changes, steaming and contact with cosmetics, hairspray, perfume or household chemicals. Your amethyst jewelry may be cleaned with a soft-bristled brush or a cloth with plain or soapy water.
