- Title
DIASPORE "Vein" in Sapphire.
- Authors
Rockwell, Kimberly
- Abstract
The article discusses the gemological properties of a 3.96 carat blue cushion cut sapphire submitted to the West Coast laboratory for identification. Microscopic examination revealed that a distinctive circular fracture breaking the surface of the pavilion was filled with a material that had a lower surface luster than the surrounding corundum. It was noted that the filler material contained numerous irregular thread-like voids that did not resemble the patterns and inclusions present in glassy residues.
