This is a plate of fluorite crystals with a saturated yellow colour. To my eye this one seems to show a little more hue change than some others depending on the light source – under halogen lighting, it is a rich honey-golden colour, it’s a bit brighter under daylight and it’s a brighter yellow under mixed LED lighting (3500-5000 K colour temperature). The crystals are translucent, with many little glowing internal reflections under the lights. Small amounts of pyrite are associated with the fluorite. In very good condition, a few small chips and some incomplete crystals around the periphery where this specimen was removed from the surrounding rock.
The third photo is a bird’s-eye-view, with the display-face facing upward.
A pretty yellow fluorite specimen.
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.
