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.

Check out this outstanding Top Boulder Opal Rough Parcel. An extra quality parcel of beautiful rough Boulder Opal. These are the best specimens out of several lots bought in person directly from the dude that mined it! Unusual and vibrant aqua colouring is a feature of this lot, along with blue, green sparkles and other flashes of colour. Some pieces show the veining which is an attractive feature also. Each piece has been cut to its best potential ready for jewellery or perfect as a mineral specimen in your Aussie collection.
