Mineral Species and Crystal Type

Gypsum is a hydrated calcium sulphate mineral with the chemical formula CaSO₄·2H₂O. It is a recognised mineral species and occurs in several natural varieties, including clear selenite, fibrous satin spar, desert rose formations, massive gypsum, and coloured gypsum specimens. Red Gypsum is valued for its warm natural colouration, which is commonly associated with iron oxide staining or iron-rich mineral inclusions within or around the gypsum.

Gypsum belongs to the monoclinic crystal system and can occur as tabular crystals, bladed forms, fibrous masses, granular material, compact nodules, or layered evaporite deposits. Depending on how the specimen formed, it may show natural crystal faces, cleavage surfaces, rough matrix areas, compact growth, or earthy surface texture. These features make gypsum an interesting mineral for both collectors and educational geology displays.

Colour, Texture and Natural Appearance

This Red Gypsum specimen displays the appealing earthy colour range associated with iron-influenced gypsum. Natural tones may include red, reddish orange, terracotta, rusty brown, salmon pink, peach, cream, or pale beige areas. The colour may appear as an even surface tone, internal shading, natural staining, banding, or patches across the specimen depending on the mineral growth and later geological conditions.

Gypsum can show a pearly, silky, vitreous, or dull lustre depending on its form and surface texture. Red Gypsum specimens may display fine crystalline areas, rough natural surfaces, small cavities, layered growth, cleavage marks, iron-rich coatings, or mineral contact zones. These natural variations are part of the specimen’s genuine geological character and help make each piece unique.

Geological Formation

Gypsum commonly forms in evaporite environments, where mineral-rich water evaporates and leaves behind deposits of calcium sulphate. These settings may include ancient shallow seas, salt lakes, lagoons, inland basins, desert flats, and sedimentary environments with high evaporation rates. Over long periods of geological time, gypsum can develop as beds, veins, nodules, crystals, rosettes, and compact mineral masses.

The red colouration in Red Gypsum is typically linked to iron-bearing minerals, especially iron oxides such as hematite or related earthy mineral material. These iron-rich components may be present during formation or introduced later through groundwater movement, oxidation, or contact with surrounding sediment. This gives the specimen its distinctive warm colour while preserving the mineralogical identity of gypsum.

Collecting, Display and Care

This Red Gypsum crystal specimen is ideal for display in a mineral cabinet, on a shelf, desk, specimen tray, geology collection, natural history display, or educational rock and mineral set. Its warm colour and natural texture make it a visually appealing display piece, especially for collectors interested in evaporite minerals, calcium sulphate minerals, and colour-varied gypsum specimens.

Gypsum is a soft mineral with a Mohs hardness of approximately 2, so it should be handled carefully. It can be scratched by harder minerals, metal objects, quartz, or abrasive surfaces. Avoid soaking the specimen, exposing it to prolonged damp conditions, using harsh chemicals, or cleaning it with abrasive cloths. To preserve its natural surface and colour, gently dust with a soft dry brush or wipe lightly with a soft dry cloth.
