: sterling silver and 2 amethysts. Size 7.
This ring was cast using a very primitive method called steam casting. This gentleman has an excellent tutorial, [link]
. Steam is a method as ancient as the Egyptians. It is low tech, requires no major purchases of equipment. Using a Coleman camp stove with a flower pot, and a tuna can with paper towels, you can make quality castings that rival vacuum or centrifugal casting.
I set two amethysts into each side as eyes for this ouroboros.
