Ocean jasper cabochon, 37.7X22.7mm keystone

This stone is 5.6mm thick and an approximate weight of 37cts. A nice shiny polish on both front and back.

Ocean jasper or Orbicular ocean jasper from Madagascar. Also, in general, the stone this cabochon was cut from, had many crystal filled micro cavities, some below the surface, and some above. Making the stone really sparkle in the sunlight!
