A high speed drill was used to make the hole for the sterling jump ring and to flush set the two 3mm garnet gemstones. The most valuable of the chalcedony family is set in the sterling bezel; 6mm Australian bottle green chrysoprase. This form of green chrysoprase is most often mistaken as jade. The free form sterling silver that is cold enameled to the front of the Agate is a result of a casting spill over. Most of these shapes are formed within the rocks that support the casting molds. All that I have kept have interesting features. Included is a 24" sterling silver chain. This will command attention from and for all who wear this magnificient piece of art.
