Comment: Masterful precision-cut, free of inclusions under the lens (not easy for almost 20x20mm). Glittering lively and sparkles with every movement. Why only 'very good'? Because its purple is bright (light 40) for 'ideal' amethyst. However, our lapidary extracted the very best from the natural rough. No window, no inclusions, no treatments. Should you be looking for an massive untreated pendant-gem in bright purple with lots of luster - la voila (no french keyboard)! A security-oriented pendant with six prongs would pay for the deep color you didn't want in the first place. With today's gold prices, big designs may be made in silver too. See the close-ups where precision-cut and light-reflection play their own games. Too big for any ring under size 12.
