4.1" Blue Barite, Quartz, Marcasite and Pyrite Association - Morocco

 
 
This specimen contains pyrite, quartz and bladed blue barite. The pyrite has a beautiful luster to it, as well as the sharp marcasite crystals that are aggregated in association with the pyrite. The barite has a blue coloration and a bladed formation. Quartz crystals can be found in multiple locations throughout the specimen, seemingly acting as a glue between the other crystals.

Comes with an acrylic display stand.

Barite, commonly spelled Baryte is well-known for its great range of colors and varied crystal forms and habits. It is a heavy mineral consisting of barium sulfate, and typically has the chemical formula of BaSO4. The barite group consists of baryte, celestine, anglesite and anhydrite. It's generally white to colorless, and is the main source of barium.

The mineral pyrite or iron pyrite is commonly referred to as Fool's Gold because it's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, Pyrite was sometimes mistaken for Gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and habits. Smaller (druzy) crystal aggregates may give off a beautiful glistening effects, and larger crystals may be perfectly formed, including fascinating cubes, penetration twins, and other interesting crystal forms.

Silicon Dioxide, also know as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
