Natural Dogtooth Calcite Slab 11 Inch COA Included

Description

11″ Natural Dogtooth Calcite Slab – Large Crystal Display Specimen

This striking 11-inch Natural Dogtooth Calcite Slab is an impressive mineral specimen featuring classic sharp calcite crystal formations preserved across a broad, visually dramatic surface. Dogtooth Calcite is instantly recognisable for its pointed, tooth-like crystals—typically forming in large, scalenohedral shapes that rise from the matrix in radiant clusters.

You will receive the exact slab shown in the photographs. A 1 cm scale cube is included to provide accurate size reference, with all full measurements visible in the images. This is a carefully selected, high-quality display piece chosen for its structure, crystal detail, and visual impact.

All of our crystals are 100% genuine specimens, and your purchase includes a Certificate of Authenticity.

Geological Background – Formation of Dogtooth Calcite

Calcite (CaCO₃) is one of the most widespread minerals on Earth and forms in a vast range of geological environments. Dogtooth Calcite develops specifically in hydrothermal veins, caves, open pockets in limestone, and mineral-rich cavities where conditions allow for unrestricted crystal growth.

As calcium-rich groundwater circulates through fractures and voids, calcite precipitates from solution, building crystals layer by layer. When these crystals grow into elongated, sharply pointed scalenohedral shapes, the formation is known as Dogtooth Calcite—named for its resemblance to the pointed teeth of a canine.

Over millions of years, tectonic movement, fluid chemistry, temperature shifts, and pressure changes contribute to the diversity of forms found in calcite deposits. Calcite’s ability to crystallise in more than 800 known forms makes it one of the most structurally diverse minerals, but Dogtooth Calcite remains one of the most dramatic and recognisable.

Crystal Type, Mineral Structure & Physical Characteristics

Calcite crystallises in the trigonal division of the hexagonal crystal system, with Dogtooth Calcite specifically forming scalenohedral crystals—a geometric shape with long, tapering faces that end in sharp points.

Key features of this 11″ Dogtooth Calcite slab include:

• Sharp, elongated crystal points arranged in natural geometric clusters
• Warm, earthy colour tones, which may include creamy white, honey brown, tan, or reddish mineral shading
• Translucency, with some crystals allowing soft light to pass through their terminations
• Subtle internal veils and banding, created during mineral growth
• Fine natural luster, ranging from satin to glassy, depending on the angle of light

Calcite is known for its double refraction property—when clear enough, the crystal splits light into two rays, producing a visually striking optical effect. Some Dogtooth specimens show faint zoning or internal clarity zones that enhance their visual depth.

Locality Geology & Associated Minerals

Dogtooth Calcite is often associated with:

• Quartz
• Galena
• Sphalerite
• Fluorite
• Barite
• Dolomite

These minerals frequently occur in the same hydrothermal systems or carbonate-hosted deposits. The slab structure suggests formation in an open cavity or bedding-plane pocket, where crystals could grow outward freely before being preserved in solid rock.

The geology of such deposits typically includes limestone, dolomite, or sedimentary host rock, altered by mineral-rich groundwater movement.

Decorative, Collecting & Display Appeal

Due to its sculptural form, Dogtooth Calcite is prized by both mineral collectors and interior decorators. This 11″ slab offers exceptional display presence and is ideal for:

• Mineral specimen collections
• Home décor centrepieces
• Shelf, cabinet, or wall-shelf displays
• Office, studio, or gallery environments
• Photography, artistic inspiration, or educational use
• Gifts for mineral and geology enthusiasts

The intricate crystal landscape creates a natural focal point, drawing attention from across a room.
