Description

Pink crystal aggregates of the extremely rare rubidium mineral rubicline in a matrix of white pollucite, another rare mineral , in this case a cesium mineral.

Rubidium minerals are extremely rare in Nature since only 4 mineral species (aleutite, ramanite-(Rb), voloshinite and rubicline ) from almost 5500 known mineral species are rubidium minerals (source Mindat), so it is a real rarity, almost never seen on the mineral market.

Cesium minerals (for the matrix of pollucite) are also very rare in Nature since only 28 cesium mineral species are known !

Analyzed specimen, see copy enclosed.

Two Rb and Cs rarities in a single specimen.
