Comment: Permitted into our stock: Oiled emeralds. (Please read here if you want to know more)

Fullest and most dense green with some crystalline inclusions. Not deep but without window, therefore a serious face-up, especially for Sandawana where every gem over one carat is a rarity. Here 8mm square in a deep vivid green, without yellow and just a dash of blue. Comes with a letter of origin from the honorable German non-profit institute DSEF. One of the most legendary emerald origins in history, for a long time equal to Columbia until production ceased 30 years ago. Since then, only few reach the open market every year (and from us). Only minor surface oil, and that probably rather a result from cutting and polishing not from dedicated treatment, but the labs have their reasons to be stubborn in this. Full ring size even for a gent's ring up to 9 and with a think bezel or halo over 10. Few Sandawana make this possible and are then above $10k. Color-Color-Color as it must be in emerald.
