Rough green amethyst rings in a sterling silver prong setting. This lovely form of green quartz is more correctly known as “prasiolite”, as technically the word “amethyst” is reserved for purple quartz, but whatever we call it, this is still a beautiful stone. The first ring shown is a bit larger than US size 8 1/4 (UK size Q 1/2), and weighs a total of 5 grams (less than 1/5 of an ounce). The semi-precious gemstone is 18 mm (3/4 of an inch) long, and 12 mm (1/2 an inch) across. The band is about 3.5 mm wide (over 1/8 of an inch). The second ring available is US size 8 (UK size Q), and weighs 5 grams (less than 1/5 of an ounce). The stone is 16 mm (2/3 of an inch) long and 13 mm (1/2 an inch) across. The band is about 3.5 mm wide (over 1/8 of an inch). These rings are not made by me; they come from one of my long-time suppliers, and are available here to complement my handmade pendants and earrings in the same materials.
