Crystals are prismatic, very well developed. The main one is doubly terminated, with triangular growth pits on terminations. In addition to its quality and esthetics, we note its variable color mainly blue but with reddish zones.

TH77J3: Corundum with Oligoclase and Biotite
Tabular crystals with geometric striations of growth. Color is very intense, especially enhanced when the specimen is under a strong light. Crystals are in a Biotite matrix very rich of Oligoclase. We are very pleased because it has been possible for us to precisely certify the locality of origin, which is not always easy.
