OKK-127

OKK-127    Fluorite    Madoc, Ontario, Canada.  Collected by Michael Walter, Ex. Michael Walter collection.  This is the nices piece from a four day dig.  The base color of the crystals is a rich blue but that is mostly masked by clear, tan and green overgrowths.  Only damage is a couple small spots have the overgrowth chipped off. Excellent quality for an unusual and unique gash vein find just off the highway between Madoc and Marmora, Ontario.  Almost everything recovered from the excavation were smaller yellow cubes or single crystals.  This was one of the very few plates to hold together naturally and the largest by far.  Luster is better in person.  $240
