  • Multiple honey-yellow ettringite crystals projecting from a dark, nearly black manganese-rich matrix. The hexagonal crystals vary in size and are arranged in an eye-catching three-dimensional pattern against the contrasting dark background, with a few showing minor damage.

Attractive display of rich yellow ettringite popping out of dark manganese-bearing matrix. Most of the crystals are pristine though we’ve adjusted the price to reflect a couple of damaged crystals. The contrast of color and the three-dimensional arrangement certainly make for an attention grabber.

Ettringite occurs within manganese-rich sedimentary deposits at the Wessels Mine. The crystallization sequence produced exceptional hexagonal prismatic crystals through low-temperature hydrothermal processes involving sulfate-rich solutions interacting with calcium-aluminum minerals in a carbonate host rock. The specimens exhibit remarkable development of colorless to yellow crystals reaching several centimeters in length, often forming distinctive radiating clusters.
