I have been playing with ways to create the random but orderly textures found in microphotographs of cross sections of plant stems. This fine brass mesh is altered then sandwiched between two sapphire sheets using a special glass epoxy. The resulting piece is then cut and polished like stone and set in silver with brass discs.
Silver chain and handmade hook clasp, adjusts 16-19". The silver is tarnish resistant and the brass is sealed, avoid chemical cleaners and abrasives but it can be cleaned with a polishing cloth.
