These are Natural Mined Emeralds.   Approx. diameter: 2.3-2.5 mm, faceted rounds.  Very rich green color. Untreated stones.

This was a parcel of commercial grade natural emeralds in small round, faceted cuts.  Hand cut stones vary in dimensions and faceting. 

There is some natural matrix as with many emeralds.  Green Color is very rich.  Some stones are transparent and some slightly translucent.

This is a more commercial grade of natural cut emeralds and are priced accordingly.  I am not sure of their origin. 

Good for small jobs or repairs.
