Rhodochrosite

A hard-to-find thumbnail size gem Rhodochrosite! There are three major prismatic, scalenohedral crystals with white phantoms and naturally flat terminations. I recently pried this out of a friend's thumbnail collection with a generous trade. It has the code "TCRT2551" on the underside (my friend didn't know which collection it came out of). It weighs 21.76 carats = 4.35 grams. No damage, and there is a noticeable change in the color of the Rhodochrosite crystals... Before the white phantom it is a deeper flawless red, after the phantom, it becomes a lighter red.
