Amethyst heart-shaped CZ stone in a bezel setting. Like a toy party favor ring -- but all grown up.  Sizing: This ring fits true to size. If you're in between sizes, please go up to the next whole size.  Can wash hands carefully; not recommend for daily shower wear due to abrasive contact with loofahs and interaction with chemicals we can't account for. More information at bottom of page.  Ready-Made pieces are hypoallergenic and biocompatible (won't harm living tissue) - #NoGreenSkin is a guarantee. We use #NoGold and no mined precious metals ever, using instead Star Steel (from the 316L medical/stainless family) and a super strong ceramic found naturally only on the surface of asteroids. We make ours inside a vacuum. Our eco-friendly, high-tech coating process uses no water, emits no fumes, and produces no byproduct. Say it with us: #IWantToBelieve in an alternate reality for jewelry.  Size 7 ring weighs approx. 1.1 grams Center stone measures approx. 6.4mm x 6.5mm x 4mm tall.
