These series of rings are all individually sculpted, and are made from a solid piece of black acrylic plastic, and vintage Bakelite. after the two pieces are joined together the block gets whittled down it's final shape.. this particular one ihas a piece of marbleized midnight blue bakelite.
This particular ring is a size 4.5, however i can remake it in a larger size.
this design can be duplicated with various color tops, please contact me to see what options are available.
