These HUGE CRYSTALS have a pleasing pale yellow color to them and are translucent. They have been XRAYED and are montebrasite and not the species amblygonite with which there is often confusion in labelling. Admittedly, there were some on matrix, but they tended to be clunkier overall and were priced higher, so I just went for one nice example of the single crystals. This one has a fully developed, wonderful top termination. The piece displays nicely from either side, though one side has a rich coating of kosnarite on it (orangey, small crystals) occurring as a thin attached plate that can be popped off if desired. Interesting and attractive new material from Brazil! 8.5 x 7 x 3 cm
