Rich yellow/amber fluorite with localized purple hues. The interior is absolutely transparent to the point where one can view internal etching associated with the purple areas. These are very rare from the Denton Mine and really for the district overall. It is exceedingly rare to find a group of these crystals as the etching and fluid movement associated with this type of fluorite was so intense that the crystals were nearly always found loose as singles. Advance mining ca. 1981. In excellent condition. Tolonen Collection. Entered into Ross C. Lillie Collection database as RCL2537.
