NG13E8: Crandallite after Fluellite
A mineralogical rarity. The Crandallite has been totally substituted by the Fluellite. This one is even more interesting given the size of the crystals and the fact that they are well separated from each other and are on the contrasting dark matrix.

Specimen size: 8.7 × 4 × 1.7 cm = 3.43” × 1.57” × 0.67”

TC140NL: Crandallite after Fluellite with Metavariscite
A mineralogical rarity. Crandallite has totally replaced the Fluellite crystals. Increasing the interest of the specimen is the remarkable size of the crystals and the fact that they are quite separate, contrasting with the dark matrix, very rich in Metavariscite.
