Crystallized minerals

L'adamite est un arséniate de zinc avec des beaux cristaux aplatis, rosettes en forme d'éventail. Sur cet échantillon, ils sont jaunes tirant sur le vert, bien formés et visuellement se détachent bien de la gangue. Formule chimique : Zn2AsO4OH Dureté : 3.5 Densité : 4.4 Clivage : bon Eclat : vitreux Florescence : oui Dédié au minéralogiste français Gilbert Adam (1795 - 1881)

cobaltocalcite a light purplish-pink hue, featuring small, evenly distributed crystals across the surface with a thickness of approximately 1 cm. The crystallization is botryoidal.

The piece has a cut base to allow it to stand upright for display.

A beautiful amethyst druse forming a cluster of large crystals ranging from light to deep purple.

The desert rose is an evaporite. It is a gypsum aggregate. The way its constituent elements bond together is similar to the arrangement of a rose's petals.

Desert sand provides these building blocks (sand, gypsum, or hydrated calcium sulfate), and the desert rose—also known as a sand rose—forms through the evaporation of capillary water from the soil.
