A group of sharp fluorite crystals on a thin plate of matrix, this piece features some of the finest yellow among the lot. Under halogen and daylight, the fluorite crystals are a rich honey yellow. Under a strip of mixed LED display lights (3500/5000K colour temperature) or under any higher temperature LED, the yellow is brighter. The fluorite crystals (up to 1.2 cm) are transparent-to-translucent, with good lustre. Very fine lines of purple phantoms are visible upon close inspection. In excellent condition, most crystals are without any damage, a couple of incomplete ones at the right-hand and back periphery. A beautiful specimen with saturated colour.
About These El Hammam Mine Fluorites
The El Hammam Mine has long been a well-known locality for fluorite specimens. This recent small pocket has produced unusually fine sharp yellow crystals.
The hue of these fluorites varies, depending on the light source (common for fluorite), from a warmer honey-yellow under halogen, to a slightly brighter yellow in daylight and even a bit bolder under cool-temperature LED lighting. (This effect is different with each specimen, some show it more and some less). The depth of the yellow colour also varies from one specimen to the next thanks to the fine, faint purple phantoms in many of the crystals.
