This specimen has a bed of crystalline quartz with crystals of bertrandite, fluorite and fluorapatite set on them. The fluorite was deposited in two generations with sharp octahedral crystals to 1.8 cm across first followed by a micro crystalline deposition. The bertrandite crystals have a frosting of the smaller fluorite crystals. Very lustrous and gemmy blue fluorapatite crystals to 1 cm are found scattered about the specimen also. Several are doubly terminated.

  

This specimen has quartz with crystals of bertrandite, fluorite and fluorapatite set on them. The fluorite was deposited in two generations with sharp octahedral crystals to 1.3 cm across first followed by a micro crystalline deposition. Bertrandite have a frosting of the smaller fluorite crystals. Blue fluorapatite crystals to 0.8 cm are found scattered about the specimen also.
