Physical properties

Mohs hardness of 7 (for embedded amethyst chips); purple to violet coloration caused by irradiation and trace iron inclusions; vitreous luster inside a clear resin shell; trigonal crystal system in natural form.

Formation & geological history

Amethyst forms in geodes within volcanic host rocks and hydrothermal veins. These small tumbled chips were mined, gathered, and set into a clear synthetic polymer resin mold shaped like a sea turtle.

Uses & applications

Used primarily as decorative art, giftware, paperweights, or metaphysical/orgonite objects.

Geological facts

Amethyst is the purple variety of quartz and is the birthstone for February. In ancient times, Greeks believed amethyst could prevent drunkenness.

Field identification & locations

Recognizable by the characteristic purple color of the quartz chips encased within a transparent molded plastic/resin body. Amethyst is widely found in Brazil, Uruguay, and Zambia.
