Big, zoned purple Fluorites crystals with sharp edges and classic face modifications. As is typical of some english Fluorites like this there is daylight fluorescence. The outer edges of the cubes are clear while the center is a milky white to pale purple. In exceptional condition damage wise, there are a few dull Galena crystals with Goethite overgrowth that adding contrast. From an older collection, this was collected long prior to 1970. The largest cube is over 5 CM diagonal and the condition is excellent damage-wise.
A classic daylight fluorescence Fluorite from Weardale. In fine condition with a large twin (2.8 CM diagonal) prominently on top of a mound of smaller, sharp Fluorites. Good transparency and luster, there are a few phantoms in the larger crystals. A choice example from this once prolific region and a fine textbook quality twin.
An old well formed and classic Blackdene Fluorite from the collection of Warren Johansson. Warren obtained this piece in an exchange with Harvard in 1938, so it is clearly a vintage specimen. The cubes reach 4.2 CM in diameter and have good sharp edges. Several crystals display internal cleavage planes but the exterior shapes are intact and in quite good condition. Minor edge wear is noted on the outside edges but the main crystals in the center are undamaged. The Galena is on the reverse side so will not be in any logical dispaly orientation.
