RTD The top of this specimen is honeycombed with openings that contain a dozen and a half, or so clusters of grey-blue koettigite crystals. The Koettigite crystals are sharp, well terminated crystals. This is one of the relatively rare minerals that occurs at Ojula Mine, collected many years ago. Accompanied by a Ward's Science Establishment label. Excellent!
