The violet-purple gemstone Amethyst (a variety of quartz) is the Birthstone for February. It is also the Zodiac stone for the constellation of Pisces, the gemstone for the 4th, 6th, 17th, and 33rd Anniversaries, is mentioned in the Bible, and is the Day Stone for Wednesday.
Cut gems of amethyst are sometimes graded using the terms: Siberian, Uruguayan, or Bahain to represent high, medium, and low grade respectively, regardless of the actual source. Because of the patchyness of the color distribution in the crystals, Amethyst is often cut as brilliant round cuts to maximize the color. Other cuts can be used when the color is better distributed. Amethyst may be cut as beads or tumbled as pebbles, then drilled and strung into necklaces and bracelets. It may also be wire-wrapped for pendants.
