This is a cluster of blue bladed barite crystals that formed in association with small and large marcasite crystals. It was collected from the Bou Nahas Mine in Morocco. It comes with an acrylic display stand.

About Barite (Baryte)

Barite is a barium sulfate mineral (BaSO₄) known for its high specific gravity, which makes it unusually heavy for a non-metallic mineral. Typically forming in tabular or bladed crystals, barite can also appear in massive, fibrous, or nodular habits. Its colors range from colorless and white to shades of blue, yellow, gray, or brown, often influenced by trace impurities. Barite commonly forms in hydrothermal veins, sedimentary rocks, and as a gangue mineral in lead-zinc ore deposits. It is widely used in industrial applications, especially as a weighting agent in drilling muds for oil and gas exploration. Its striking crystal formations and vivid hues also make it a popular mineral for collectors.

About Marcasite

Marcasite is an iron sulfide mineral with the chemical formula FeS2. It is similar to pyrite in both its chemical composition and appearance, but it forms an entirely different crystal structure and is much more reactive to humidity. It is often found within sedimentary rock and hydrothermal deposits, and at one point was used for its sulfur content.
