Pietra Dura or Parchin kari is the art of making beautiful pieces with stone inlays... I made a pendant with Cold porcelain, inspired by this style of work.
Obviously, the process is not anywhere near as complicated as inlaying stone into a base piece, by painstakingly carving out shapes and then grinding and fitting pieces into the hollows..
The whole design filled with white Cold Porcelain and then smoothed out. I also put in three holes, one at each end and one at the center of the portion that would face down. At this stage, it was left to dry for about 24 hours.
Once it was dry, the edges were sanded, and then the inlay work was painted . White portions with a touch of brown to indicate white marble. Blue, grey , black and gold for Lapiz Lazuly and banded green in shades, for Malachite. The edges were given gold for an ornate look.
Glaze was applied and left to dry. Then the necklace was made by stringing a rectangular glass bead on each side and double strands of beads in off-white and Green, with gold spacers, to duplicate the shades of the white marble and malachite.
