BURMESE BLUE SAPPHIRE PARCEL
BURMESE BLUE SAPPHIRE PARCEL. Great coloured natural crystals. We collected these from Myanmar many moons ago.
Location:
Mogok, Myanmar.Dimensions:
9 Pieces total weight, 30g.Aluminum Oxide
Al2O3.Corundum is called Sapphire except red Sapphire which is called Ruby. The word sapphire comes from the Greek word for blue, sapphirus. Only a few hundredths of a percent of iron and titanium can cause the colour, and the more iron the corundum contains, the darker the blue. A rare sapphire is a Padparadscha which is a pinky peach colour, found in Sri Lanka. The best shade of red for a Ruby is Pigeon Blood Red. Ruby can be any shade of red up to almost pink.

HUEBNERITE QUARTZ CRYSTALS
Great looking Metal Specimen of Huebnerite Quartz Crystals, showing amazing crystal formations protruding out of the interlacing quartz matrix. Slight translucency on edges of Huebnerite crystals with some minimal yellow sulfur coloured oxide on surfaces or protected crevices and in the Quartz. This is a very collectable piece. Huebnerite is an ore of Tungsten. Tungsten is used to make fake Gold bars. That is because Tungsten has the same specific gravity as gold does. The best way to test for this type of fakery is to drill a very small hole in the bar.

CLEIOPHANE GALENA CRYSTALS
A stunning Cleiophane Galena Crystal Specimen on a Quartz matrix. Featuring many well formed crystals of Cleiophane – some on twinned Octocube Galena crystal forms. A sprinkling of micro Chalcopyrite is noticeable. Cleiophane is the gemmy or purer version of Sphalerite, sought after for its rarity and beauty. An outstanding addition to the metals cabinet for a serious collector. A real wow piece, my photos don’t do it justice. Not common Cleiophane or twinned Octocube Galena to come by and at a bargain price. The location is also classic of where some of the best Sphalerite, Galena and Quartz specimens are from. Almost forgot to mention some amazing Mangano Calcite comes from here too.

A single partial crystal with laminated structure, minor surface Pyrite and some Calcite. An interesting difference between Pyrite and Pyrrhotite is a magnet will stick to Pyrrhotite but not to Pyrite. Please read the interesting details below about weakly magnetic and two minerals in one.

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.
