Simply a fabulous specimen from the Barbara Cureton collection. The specimen is a nice light blue. Tilting the specimen back and forth produces an amazing shimmering reflection. There are actually two main crystals, the longest is 10cm, the one behind it is 8cm. Excellent piece, no damage, stands on its own, perfectly. There are also nice micro Calcite crystals on the backside. Fingers not inlcuded.

Not only comes with the hand-written standard collection card from Cureton, but with an old Scott Willaims label. On the Willaim's label it states: "from a water course along the Naica fault (1981).
