SPINEL4

The crystal is a rare Mackle twin habit. On one face of the octohedron two twinned spinel crystals have grown. So its actually three intergrown spinels that weigh 9.90 carats. I've paired it with a facetted spinel that weighs .48 carats (.6 x .4 cm). No visible dings or damage (there are natural "contacts," in the form as it grows typically in marble).
