Amano Studio is a small, woman owned jewelry brand and zero waste production studio based in Sonoma California. We partner with a handful of old New England workshops that give us access to archives of 70+ years of molds and tooling which allows us to resuscitate genuine vintage design as those designs cycle back into fashion. We also salvage "dead stock" vintage from East Coast factories that have closed. We also work with a small workshop in Seoul South Korea that makes our Miyuki Japanese Seed Bead collection. About this product Cast in a warm, earthy jeweler's brass, this Crossover Ring with hammered texture, is polished to perfection. It is cast in a size 7 but is adjustable which makes point of purchase much easier! Brass will oxidize over time but can be polished up with a jeweler's cloth or with brass cleaner. 100% made in the USA.
