This large thumbnail specimen consists of a chunk of massive Hackmanite, a variety of Sodalite. It has a very noticeable pink coloration in one area that fades to white at the opposite end of the piece. When exposed to longwave UV light, it glows a rather bright pink-red coloration. Such exposure is the cause for its pink color- this color may fade in sunlight, but indoor lighting seems to have little effect on it. It is the only piece that I have seen so far where the color change from white to pink has lasted for more than 3 hours.
