The White Queen Mine is one of the most famous San Diego County pegmatite mines and has produced a wide and unusual variety of mineral species. Here is an unusual, but very showy one. This cabinet cluster of quartz crystals is richly included with pink montmorillonite. One side is water-clear, has been polished and you can easily see the montmorillonite in the interior. The other side of the cluster is glassy and frosted. The base has also been sawed and polished. Ex. Bill Larson San Diego County Pegmatite Collection. A classic combination specimen from the White Queen Mine.
