Item details 5 out of 5 stars. (66) reviews Shipping & Policies Gorgeous Tangerine Quartz ring that has been electroformed with a very thick, bubbly layer of copper. Size 5-5.25. Measures 3.5 x 2 cm. Electroforming is an alchemical process, layers of gorgeous copper are formed over the area conductive paint is applied to, creating the beautiful jewelry you see here. The entire process often takes several days to complete a piece. Prior to going through a copper bath, I hand-sculpt the piece. After the bath, I hand paint on a patina to add depth and contrast to the copper and then polish. Please do not expose to water. Copper oxidizes naturally overtime and water is one of the ways this natural process speeds up. Lotions, perfumes and other chemicals may also accelerate oxidation. Please be aware that since this ring is copper, it may eventually turn your finger green, which is a natural reaction with copper and can be washed off.
