Scroll to read more about our matte black coating. Sizing: This ring fits true to size. Please select your usual size. If you're in-between sizes, please select the next full size up. For example, if you're Size 9.5 or 9.75, please select Size 10. For all colors, 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. Matte black coating will scratch over time to reveal the underlying 316L steel. We love the look, though, and think it brings a certain wear and aged effect to the rings, as they begin to look like blackened steel. 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 weighs Approx. 4.8 grams Width is 6mm, thickness is 2mm
