This silver porcelain ring has been made by attaching
a previously made porcelain stone which has been glazed and fired twice in my kiln.
This particular adjustable ring base is silverplated, but ring bases are also available in sterling silver or gold plate.
Height of the porcelain stone is 2.7cm or 1.3 inches.
Width is 8mm (at widest part)or 0.5 inches.
