Angelite Blue Anhydrite Mineral Specimen 20-55mm Natural Angelite Crystal Stone

Description

Natural Angelite Mineral Specimen 20–55mm

 

This natural Angelite mineral specimen, measuring approximately 20–55mm, is a carefully selected example of this distinctive blue mineral variety. Angelite is the trade name commonly used for blue anhydrite, a calcium sulphate mineral recognised for its soft blue colour and smooth massive structure.

Each piece in this listing is individually chosen and polished to highlight the mineral’s natural colour and internal structure. The photograph provided shows an example of the actual specimen you will receive, giving a clear indication of the colour, finish, and overall appearance of the stone.

The mineral displays the gentle blue tones that make angelite a popular decorative mineral specimen for collectors and display. As a natural material, slight variations in colour pattern, banding, or internal structure may occur from piece to piece, adding to the individuality of each specimen.

This crystal is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card.

Please refer to the listing photographs for full sizing and scale, with individual pieces ranging approximately 20–55mm.

Mineral Identification and Composition

 

Angelite is the commercial name for blue anhydrite, a mineral composed of calcium sulphate. It belongs to the sulphate mineral class and forms through the dehydration of gypsum under geological conditions involving heat and pressure.

Mineralogical details include:

• Mineral Name: Anhydrite (commonly marketed as Angelite)

• Chemical Formula: CaSO₄ (Calcium Sulphate)

• Mineral Class: Sulphate

• Crystal System: Orthorhombic

• Hardness: 3 to 3.5 on the Mohs scale

• Lustre: Vitreous to pearly

• Transparency: Translucent to opaque

• Crystal Habit: Typically massive rather than well-formed crystals

 

Most angelite specimens occur in massive compact forms, meaning they appear as solid pieces of mineral rather than distinct individual crystals.

Colour and Visual Characteristics

 

Angelite is known for its calm blue colouration, which ranges from pale sky blue to deeper grey-blue tones. The colour is produced by trace elements and structural conditions during mineral formation.

Common visual features include:

• Soft blue to bluish-grey colouration

• Smooth polished surfaces

• Subtle internal clouding or natural veining

• Opaque to slightly translucent areas

 

When polished, angelite displays a soft, satin-like appearance that highlights the mineral’s natural patterns and tonal variations.

Because angelite forms in massive structures, the internal patterns and colour variations often become more visible once the stone has been shaped and polished.

Geological Formation of Angelite

 

Anhydrite forms in evaporite environments, where mineral-rich water bodies gradually evaporate and leave behind mineral deposits. Over geological time, layers of evaporite minerals accumulate within sedimentary basins.

Angelite specifically forms when gypsum (calcium sulphate dihydrate) loses its water molecules under conditions of increased pressure or heat, converting into anhydrite. This process can occur deep underground where sedimentary layers are compacted.

The resulting mineral may later be uplifted and exposed through natural geological processes, allowing specimens to be collected and shaped for mineral collections.

Deposits of blue anhydrite used for angelite specimens are found in several locations worldwide, with notable material often originating from South American deposits.

Shape and Polishing

 

These angelite specimens have been shaped and polished to enhance the mineral’s natural appearance. The polishing process creates smooth surfaces that reveal the colour and internal structure of the stone.

The 20–55mm size range makes these pieces suitable for handling, display, or inclusion in mineral collections. The polished finish allows the mineral’s colour and patterns to be clearly visible under natural light.

Each piece remains a natural mineral specimen, with unique variations in colour distribution and surface patterns.

Mineral Collecting and Display

 

Angelite specimens are often appreciated by collectors and enthusiasts who enjoy minerals with distinctive colour and smooth polished finishes. Their soft blue colour makes them visually distinctive within a mineral collection.

These specimens may be suitable for:

• Mineral and crystal collections

• Geological display cabinets

• Decorative mineral displays

• Educational mineral study sets

• Collector specimen shelves

 

In some traditions, angelite is traditionally associated with symbolic or spiritual interpretations, though such interpretations represent cultural perspectives rather than scientific explanations.

Authentic Natural Mineral Specimen

 

This Angelite mineral specimen (blue anhydrite) is a genuine natural mineral selected for colour and overall appearance.
