With vibrant colors of Copper, Turquoise, Silver, and Black, each ring is made from Acrylester and starts out as a solid block. From there we turn the ring on our precision lathes to a finished ring, sanding up to a 12,000 fine grit to create a shiny finish! Since the colors of the pattern vary throughout the blank, each ring will always take on their own unique characteristics. No 2 rings will ever look the same! Dimensions are ~8mm wide and ~3mm from inner to outer diameter. It is HIGHLY recommended that you do not engage in strenuous activity while wearing your ring especially anything that will directly impact it. This will keep your ring lasting much longer!
