This is a closeup of a gypsum mineral called "Desert Rose." Here is a short explanation about this interesting mineral.
Desert rose is the colloquial name given to rose-like formations of gypsum or baryte crystal clusters which contain abundant grains of sand. The ‘petals’ are crystals flattened on the c crystallographic axis, fanning open in radiating flattened crystal clusters.
The rosette crystal habit tends to occur when the crystals form under arid sandy conditions, such as a shallow salt basin becoming evaporated. The crystals form a circular series of flat plates that give the rock a similar shape to a rose blossom.
This is a closeup of one of the specimens that we have in our living room. This is a gypsum mineral with sand.
