Calcite Inclusions in Unheated Ruby

Pyramidal shaped calcite crystals in this 2 Carat Unheated Mozambique Ruby peep out. The clear crystal shapes are still intact and are not deformed in any way.

This inclusion type is called an syngenetic type of inclusion and is likely to have formed at the same time as the host ruby crystal. An intact crystal such as this is strongly indicative that this ruby is a natural unheated ruby.
