RM833   Gypsum (var. selenite) with halite

Salinas de Otuma, Paracas, Pisco, Ica, Peru

A rich group of lenticular gypsum crystals forming rosettes. Some of them are well developed but with another shape, lanceolated and showing swallowtail twin. These are very transparent, defined faces and edges and very aerial disposed on the matrix. Accompanied by some cubic halite transparent and colorless crystals.
Gypsum fluorescence under ultraviolet source is excellent, but the phosphorescence is the most intense and lengthy I've never seen before. An uncommon and aesthetic combination.


Size: 9,5 x 7,7 x 4,8 cm.
Main crystal: 37 x 18 mm. (Gypsum)

Fluorescent and phosphorescent under long wave UV
