This is a superb specimen. A glassy and largely transparent yellow fluorite crystal (1.3 cm) sits nestled among smaller fluorite crystals, with a little bit of offsetting white matrix and dustings of sparkling pyrite crystals. Fine purple phantom lines can be seen in the fluorite crystals. In exceptional condition – the main crystal is perfect and there are only very minor rubs on smaller crystals and a few incomplete backs at the periphery where this specimen was attached. One of my favourites from this find.

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.
