Emerald cut Simulated Emeralds. This is the best gem we make. 40% harder and way less prone to cracking than a natural Emerald. It looks likes the very best genuine Emerald, but of course it is much less expensive. Also, remember our guarantee!! This is a beautiful pair of earrings and they are made right too.....the post is welded close to one end so that the earring displays on your ear correctly. Cheap earrings twist and end up making you look unkempt.
