1.8" Lazurite and Pyrite Crystals in Calcite Matrix - Afghanistan
This wonderful specimen contains a lazurite crystal and pyrite crystals that are partially exposed from a 1.8" wide marble/calcite matrix. This specimen was collected from the Sar-e-Sang District of Afghanistan, an area well known for its phenomenal lazurite crystals.
Lazurite is a vibrant blue mineral of the tectosilicates group with the chemical formula Na6Ca2Al6Si6O24S2. It is the blue component in lapis lazuli and is most often found in massive forms, though in some cases it does form individual crystals. Afghanistan is well known for several deposits that produce phenomenal lazurite crystals in a marble matrix. These specimens are highly sought after by both amateur and expert mineral collectors.
About Pyrite
The mineral pyrite, also known as iron pyrite, is commonly referred to as Fool's Gold because its 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.
It is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and habits, including cubes of all sizes, penetration twin cubes, pyritohedral clusters and as small druzy crystals that can exhibit a beautiful glistening effect.
