A simply incredible specimen of GEM jeremejevite from a most unusual locality, and with a most unusual color, it had to be x rayed to confirm: Analysed and confirmed by the world's top expert on rare gem species, Dr. George Rossman at Caltech. This is a significant crystal for the species and (obviously) a competitive level thumbnail that is different from all the rest, the typical and now all too common blue material from Namibia of which there are now dozens of fine thumbnail crystals in existence. Not so, for this straw-yellow surprise. 14.55 cts or about 3 grams.
