Fossil shell that has been replaced by translucent golden agate. These are found on the surface, having weathered out of the surrounding rock formations.

Thaumasite is a rare mineral in the Ettringite group, the best were found at the N'Chwanning.

Crystals are a transparent yellow and reach 5mm in diameter. White tufts of Xonotlite are dispersed between the Thaumasite crystals.
