Love is Love. Show your support for your LGBT loved ones with this Serinium® Rainbow band. Serinium® inlay rings are custom made to order. First, we precision grind a 5mm wide groove with a diamond wheel. Once the groove has been cut, we then carefully insert the inlay and then apply our proprietary coating to ensure the inlay is protected from the elements. The coating is then polished with high-speed buffing wheels to attain a highly polished finish. Sizes are available from 5 to 16 in full and half sizes.
