Comment: Newly permitted into our stock: Oiled emeralds. (Please read here if you want to know why.)

Neon blue-green emerald in 6x4+mm, and almost no inclusions(!). One tiny area in the upper half is lightly included, visible only under the lens; all else shines with the finest clean beryl crystal. Note in the close-up below: You can actually see through the center in this angle (strictly speaking this is a window but in such a color and size it remains hidden from the eye). 'Fine color and Zimbabwe' documented on the IGI lab report (comes with the gem in the original, free of charge). Over half a carat is considered big in this famous emerald type with its top-of-world chromium content. Minor surface oil only, extremely visible even from a good distance. Fills any ring up to size 10. Compare with OSE037: clearly more blue in this 0.56 and a brighter, more aggressive, shade, called 'open' in emerald-speak.
