The Cell Collection has piano key ivory inset in sterling silver textured forms. Stones are set in 18k gold bezels. The ivory came from my parents 1923 pedal organ. They were trying to get rid of the organ but no one would attempt to remove it from the house. We started dismantling it screw by screw, and I luckily ended up with the keys. Stone options: topaz, amethyst, peridot, garnet, ruby Click on a small image to the left for a description of that item
