A rare matrix specimen with two crystals, one to 2 cm, perched isolated on matrix and standing up dramatically from it! 98 grams weight. This piece has the two sharp crystals actually floating in muscovite layers that seem to have covered the bottom of a compound crystal formed previously, into which the crystals atop settled and sunk in a bit. Its very appealing, overall, and again is one of the very few matrix specimens we have from here at this time.
