Fluorescent Specimens, Metal Specimens, Minerals of the World, Rock 'n Slabs, Slabs, Top ShelfWILLEMITE FLUORESCENT SLAB 05
A stunning specimen of Willemite Fluorescent Slab 05 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.

PYRRHOTITE SPHALERITE QUARTZ
An amazing combo of three great minerals Pyrrhotite Sphalerite Quartz! This location is known for its incredible metal/mineral specimens and this is no exception. An affordable, collection-worthy piece. This specimen displays many classic barrel shaped crystals of Pyrrhotite and is from old stock. Pyrrhotite crystals are rare and hard to come by.
Location:
Dalnegorsk, Russian Federation.Dimensions:
4.9cm x 7.3cm x 6.2cm, 215g.Pyrrhotite: Fe7S8, Also given as Fe1-x (x = 0 to 0.17).
Named in 1847 by Ours Pierre Armand Petit Dufrenoy from Greek “pyrrhos”, flame-coloured. Pyrrhotite has some unusual characteristics. First, it has an unusual formula. The amount of sulfur does vary by roughly 20% or 50 to 55 atoms of sulfur per 50 atoms of iron. Or is it the iron that varies? Really the same difference. Thus the unusual formula of Fe1-xS. Secondly, it has two symmetries.

SPARKLING PYRITE CRYSTALS
Beautifully simple Sparkling Pyrite Crystals with very reflective faces. Great addition for mineral, metals or pyrite collections. The mineral pyrite, or iron pyrite, also known as fool’s gold, is an iron sulfide which has the chemical formula FeS2. This mineral’s metallic luster and brass yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool’s gold. Interestingly Pyrite does not attract a magnet. This specimen comes from a premier location and sports a mini cave cavity right through.

ENHYDRO QUARTZ CRYSTAL 01
Enhydro Quartz Crystal 01 for sale. Here is a stunning Enhydro with multiple inclusions of what exactly is a bit of a mystery. These moving inclusions are what looks like black carbon material inside a fluid which appears clear. There are five that I have found in this double terminated quartz crystal. Some are clusters or grouping of black material. Most are sinkers – sinkers fall down and floaters float up when turned to balance gravity.
Enhydro is the name given to a fluid or gas bubble trapped inside a crystal. These little bubbles are simply fascinating, it boggles the mind as to how it got there. The liquid inside can be water, petroleum, co2,oil or others. This Enhydro has material inside the bubble that sinks when the bubble floats up – I think it looks like carbon. Like the liquid inside could be millions of years old.
