These are not emeralds but they are exact same color as raw emeralds. These are raw 'chrome diopside' faceted rondelles. When I first saw them at the gem/bead show I thought they were emeralds, couldn't put 'em down, this green deep beautiful color mesmerized me. If you see a polished diopside stone you'd think it was an emerald. Of course, they are not as expensive as emeralds, but not as cheap either. Heard they are the newest trend in jewelries now...it's the next "peridot" (which is no. 1 as the most famous in green colored jewelries).
