Description

Bixbyite is named by Maynard Bixby, who discovered the locality and the mineral. In this case it is really large, modified crystal with very good luster and sharp termination. It is perched on light matrix, minor topaz crystals are also present. The lower base of the crystal was contacted (not boken) and had no room to grow. Very aesthetic and fine sample from this famous classic locality.
