WILLEMITE FLUORESCENT SLAB 01
A stunning specimen of Willemite Fluorescent Slab showing off the brightest fluorescence of all natural minerals Willemite. This rare special specimen is short and long wave fluorescent. The dark grey metal shown in the natural light photos is Zinc ore Franklinite. The white mineral is Mangano Calcite, shows as Pink with UVA Long Wave and Orange with UVC Short Wave. The Willemite is Bright Mesmerising Green under both fluorescent wave lengths. Pics taken with shortwave, longwave, and sunlight. Very cool stuff and this is one of my very favorite rocks. This is a small high quality specimen with bright fluorescence at a bargain price. The Slab is intended as a specimen and may have natural fractures which may not make it suitable for Lapidary work.
To view this spectacular specimen’s fluorescent colours you will need a UVC Shortwave Lamp and UVA Longwave Lamp. Make sure you wear safety glasses. Willemite Franklinite Calcite is also known as the Christmas Tree Rock for the colours Green and Red. This is a quality collectable specimen with wow factor.

Carrollite was discovered in Carroll County, Maryland, and recognized as a mineral species in 1852. It is named for Carroll County. Carrollite is collected for its mineralogical rarity, rarity of sizeable crystals, unusual chemical composition as one of the relatively few cobalt-bearing minerals, high degree of cubic-crystal development, and associations in composite specimens with such minerals as quartz and calcite.

A stunning Pyrite Sun. This is a natural formation of Pyrite and something quite different to the usual more cubic looking varieties. Striations radiate out from the centre. Our Suns are hand selected at the source for their excellent quality. We are well known for our metals range and have pyrite specimens showing cubic, orbicular and octahedral crystals, as well as these suns. Pyrite (“fools gold”) is popular with all age groups. A great piece for the collector of unusual pieces. This Pyrite Sun comes with a perspex stand for display and looks even better in person.
