This stone was as much for fun as for anything else. It is a 8.47 carat prasiolite, 13.2 mm.in diameter. The pavilion had a row of narrow concave facets splitting the normal culet row facets. Then the crown was rounded up to the table instead of using rows of flat facets. Finally a number of concave facets were added to the crown.
The cameral once again sees things the do not quite match what I see. The pattern in the center is not something that I "see". and the light and dark pattern is much more subtle.
