This a cutting grade bastnaesite crystal, with a very good transparency for this species and a fine idiomorphic crystal shape, showing on top a basal pinacoid. The color change is strongly visible in changing from brownish yellowish hues in daylight to keep orangey brown in incandescent light. Beautiful specimen from Zagi- Mountains.
