Babingtonite is a dark green-black calcium-iron silicate of skarns and basalt cavities, a sought-after collector species best known in China from the Huanggang Mine in Inner Mongolia.

About Babingtoniteextended article

Babingtonite is a calcium-iron inosilicate that forms in skarns, hydrothermal veins, and cavities in basalt. Its dark green to greenish-black crystals — with a bright vitreous lustre and sharp, wedge-shaped habit — make it a prized small-cabinet and miniature collector species.

The Chinese angle

The Huanggang iron-tin skarn in Inner Mongolia has produced fine lustrous babingtonite, often with the ilvaite, hedenbergite, and quartz that characterise the deposit — adding to Huanggang’s reputation as one of the great modern skarn localities.

What collectors look for

Crystal sharpness, the deep green-black colour with its bright lustre, size (the species rarely forms large crystals), and an undamaged termination drive value. Aesthetic associations on contrasting matrix are especially prized.

About Babingtonite

Babingtonite belongs to the inosilicate class in the babingtonite group and has the chemical formula Ca2(Fe2+,Mn)Fe3+Si5O14(OH). It crystallizes in the triclinic system and holds a steady position among inosilicate species.

Identification & care

Crystals commonly develop as short prismatic, tabular crystals with complex faces; often well-formed; radial groups. Its color is typically greenish black, dark green and black. The luster is vitreous to resinous, the streak is gray-green, and specimens range from translucent to opaque. The cleavage is perfect {001}, good {010}. The fracture is uneven, which aids identification.

Collector context

Collector notes

Babingtonite holds a steady place in systematic mineral collections. Babingtonite is widely represented across Chinese provinces, including Yunnan, Sichuan, Hubei.
