From Carlos Barbosa's Personal Collection, comes this huge, gemmy, complete-all-around crystal of the extremely rare phosphate sellaite. I know it looks like a blobby white rock in the pics, but it "is what is is" and is also somewhat more visually appealing in person I can assure you. Extremely significant and hard to find, in such size! 4.2 x 2.4 x 2 cm
