Art Clay Silver is composed of 1-20 micron-sized particles of pure silver, an organic binder, and water. This combination of materials makes clay, which can be easily molded using techniques similar to ceramic hand building processes. Once the clay is completely dry it can be filed, carved, and sanded. Finally, it needs to be fired using a butane torch or kiln.

Gemstones are faceted to maximize the amount of light bouncing around in the stone and back out to the viewer. Faceting maximizes the brilliance, fire, and life of the stone. Unlike cabochons, where inclusions can add character, inclusions in a faceted gem interrupt the light and decrease the fire of the stone.
Birthstones are gemstones that signify a birth month. Every stone carries a unique meaning and historical significance. The history of birthstones can be traced back to the 18th century. Since then every culture has their own interpretation. We organize our birthstones by the American Gem Society endorsed list.
