About Amethyst - History and Introduction
Amethyst is recognized as the official birthstone for the month of February. Amethyst belongs to the macrocrystalline branch of quartz and owes its violet/purple color to iron and aluminum impurities. Without such coloring agents, amethyst would simply be transparent, ordinary colorless quartz. Like other varieties of macrocrystalline quartz, amethyst has transparent to translucent clarity and a vitreous luster. Cryptocrystalline varieties of quartz almost always occur with translucent to opaque clarity.
Amethyst Versus Citrine
Amethyst is the violet-colored sister stone of golden citrine quartz. Color-zoned ametrine is the bicolored combination of both amethyst and citrine. The only difference between amethyst and citrine is the level of iron impurities in amethyst. When amethyst is heated at high temperatures of around 470°C to 750°C, iron impurities are reduced and can turn violet amethyst into golden 'heated' citrine. Lower grade amethyst stones are often heated to produce golden colored citrine stones. Heated citrine will typically appear more reddish when compared to unheated citrine.
Identifying AmethystBack to Top
In artificial light, amethyst does not display its best color. Amethyst looks best in daylight; more precisely, slightly after sunrise or just before sunset when the light is soft and warm. Amethyst is distinguished by its violet-purple colors. The best specimens should have a deep purple color and good saturation with minimal color zoning.

Amethyst Gemstone Mythology, Metaphysical and Healing PowersBack to Top
The legend of the origin of amethyst comes to us from a Greek myth. Dionysius, the god of intoxication, was angered one day by an insult from a human and swore revenge on the next mortal that crossed his path. Aggressive tigers would carry out his wish. Amethyst, a beautiful young maiden on her way to pay tribute to the goddess Diana was to become the victim. Diana turned Amethyst into a statue of pure crystalline quartz to protect her from the tigers' brutal claws. Dionysius wept tears of wine in remorse for his action at the sight of the beautiful statue. The god's tears stained the quartz purple, creating the famous gem.

Due to amethyst having a purple-violet color, many believe that amethyst should be worn by females only. However, purple is the color of royalty and royalty has no gender preference. Therefore, it is an excellent choice of stone for men or women. Amethyst is harder than most other materials, so it is very resistant to wear and tear. Amethyst is a favorite for many jewelers because of the large sizes and shapes available.

Amethyst Gemstone and Jewelry Care and CleaningBack to Top
Amethyst can easily be cleaned with warm water and a mild soap. Wipe down amethyst using a soft cloth or toothbrush. Amethyst is quartz and although it is relatively hard and durable, there are a number of other gemstones capable of easily scratching amethyst. Therefore, take caution and do not place other harder gems near amethyst when storing, cleaning or wearing amethyst jewelry. As with most other colored stones, do not use harsh household chemicals when cleaning amethyst gemstone jewelry. Avoid prolonged exposure to extreme heat, because heat can cause permanent damage to the gemstone. When storing amethyst, always store jewelry inside a fabric-lined box or wrap it in a soft cloth. Amethyst should be stored separately from other stones, whether of whether or not they are harder or softer.
