Excellent specimen with three rather good, "large" crystals. The first pointing up is 3mm and the one on its side is 7mm. There is also another of good size and there are three smaller crystals to 2mm not shown.
You may have seen other specimens from this mine on Dakota Matrix in previous weeks. These were given to Bill Roberts of the SD School of Mines in the 1970's. Roberts later passed it on to my source. And that's all I know about this stuff.
