A REALLY fine and attractive lepidolite crystal cluster from anywhere, but especially from San Diego County. This is not just an aside or an association of muscovite here, but rather the new species boromuscovite (which, BTW, has since been granted species status) is present in abundance here as the white earthy stuff. It's a nice example, very rich. The large Lepidolite crystals in middle are 5 cm wide, and have a beautiful metallic luster, almost a lavender color to them. These specimens came out of one pocket in the 1976 "New Spaulding pocket" and were extensively studied by Gene Foord, for their unusual chemistry. Recently, this muscovite variant has been formally accepted as a new species (thanks to Dr. Robert Lauf for clarifying this for me and correcting my earlier text)
