An exciting gem from a recent and unusual find of Euclase in Bahia. What makes this deposit so special is the occurrence of a previously unknown gem color for Euclase - a bright pink slightly modified by orange highlights. Primarily a deposit for mineral collectors, very very little of the find is gem grade; indeed we have been on constant lookout for fine examples to offer. Here is the largest and finest of this effort, a superb, 1.5 + carat gem in this fascinating and lovely color. This material was written up as the cover article in a recent Journal of Gemmology.
From what we have been able to discern, few stones of this size have been cut and only smaller pieces have been seen in the market. Moreover, the rough is heavily fractured and clean stones are almost nonexistent. While essentially and eye-clean stone, this gem has a very faint series of Rutile needles that swirl inside - they soften the brilliance only slightly and seem to be a diagnostic inclusion for this find. Adding to the difficulty in getting gems out of this material is the exceptional color zoning of the crystals - intense pink/orange on the diagonal with colorless. Truly, a cutting nightmare! Quite beautifully, if you rotate this gem off-axis you can find the classic colorless ‘point’ of color zoning (see the last photo). The cutting is so good that this is not visible face-up. An attractive rarity in a fine large size.
