A plate of beautiful yellow fluorite crystals, this one features sharp cubes with good glassy lustre for this find. The crystals are translucent to transparent and the specimen as a whole is translucent from behind. Some minor pyrite dusting a few of the fluorite crystals. Very fine and somewhat faint purple phantom lines can be seen in many of the crystals. In excellent condition, a few minor rubs and a contact in the back of the larger crystal all seem to date to the end of the crystallization phase, as they evidence some recrystallization texture (visible with magnification). This is an attractive dark yellow fluorite.

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.
