TOP SPHALERITE GALENA SPECIMEN
A Top Sphalerite Galena Specimen to add to your outstanding collection. This is a great small specimen of metal crystals. An outstanding specimen with lustrous, well formed crystals of Sphalerite and Galena. This specimen is from the premier location for this mineral. A super piece, my photos don’t do it justice.

PYRITE SUN MEDIUM
A stunning Pyrite Sun Medium. 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.

Lovely Pyrite Mangano Calcite Couple. Two specimens from the same location were in an old stock box and here they are. One in a triangle crystal shape with mass coating of micro Pyrite on one side. Another light coloured crystals cluster with minor Micro Pyrite. Both of these specimens are fluorescent under the long and short of it. UVC and UVA, just for good measure a few pics showing very brief phosphorescence with a UV laser. Just the kind many crystal lovers choose over more perfect collectible pieces. A super nice piece and something different from the more commonly available.

MALACHITE PSEUDOMORPH AZURITE
A rare mineral specimen of Malachite Pseudomorph after Azurite. You can see that the Malachite is not in one of its natural forms, but instead is more like Azurite. A pseudomorph is when one mineral is chemically replaced by another mineral without changing the external form of the original mineral. In this case the Malachite has replaced the original Azurite mineral. Bright flashes of green from chatoyancy striations of the Malachite. Azurite shows good forms of chisel top tabular prismatic crystals jutting out from the matrix. Very collectible piece, both for it is a pseudomorph and a rare mineral from a great location. An excellent gift or treat for the mineral collector and a must for the Collection. For enhanced display is mounted on perspex pad, ready to go straight into your cabinet.
