Amethyst Specimens (Bulk)
NATURAL + UNIQUE + COLLECTIBLE
This is another addition to our growing Bulk Minerals collection. The Brazilian Bulk Rough Amethyst stones are an average size of half an inch. Amethyst is a semi-precious quartz made of silica. Its color is due to irradiation, iron impurities, and additional transition metals, which create a complex crystal lattice.
This crystal is sold in a 1 lb bag.
Amethyst, the birthstone for February, is one of our most popular gemstone materials. Amethyst forms in long, prismatic crystals in geodes or hallow rocks. These geodes form when there are cavities in volcanic rock. As the rock cools, the mineral-saturated water, gases and volcanic material distill and crystallize. When these crystals harden, they form amethyst. Although generally more of a deeper purple, the stone can also have a reddish-purple tinge, or a very pale purple tinge that fades into a lilac.

These half-inch amethysts make great gifts to friends, and are a wonderful start to a mineral collection!
