Olive-green double-terminated Enstatite crystal

3D ModelNoAI

Locality: Bamle, Norway

No.: 5795

Size: 8 cm x 2.5 cm x 2 cm

Formula: Mg2Si2O6 (or MgSiO3)

Description: This specimen represents a well-terminated long prismatic crystal of Enstatite. Enstatite forms series with the rare mineral Ferrosillite (Fe2Si2O6 or FeSiO3). Pure Enstatite (without any at all Fe) is not common, and pure Ferrosillite (without any Mg) is extremely rare. A common intermediary member of this series is known as ‘Hypersthene’, with a chemical formula of (Mg,Fe)2Si2O6 or (Mg,Fe)SiO3. Although the term ‘Hypersthene’ has been discredited by the IMA in 1998, it is still commonly used by many reference guides and is labeled as such in many collections.

Pure Enstatite is transparent and lightly colored; the iron content is responsible for the darker colors and increased opacity.
