Rare old Tourmaline with a distinctive yellow body color and a blue top. These are legendary and coveted from a one time find long ago. I don't recall they exact year they were found, but I saw what I believe was the bulk of the find in a dealer's room at the Desert Inn in Tucson and the Desert Inn closed back in the 1980s. It is complete and undamaged, highly gemmy in the yellow zone and the blue top shows color banding. Weighs 4.59 grams.
