I got this piece in a large lot about 6 years ago. I recently raided the stash, as these are no longer on the market. Two neatly perched sapphires are "nesting," on calcite in a black, shiny Schist. They are in good shape, with a minor abrasion on a corner of the larger crystal (hard to see). Great color for this location.
