Natural Yellow Brucite Crystal Cluster on Metamorphic Matrix · 261 ct · Decorative Specimen

This striking natural Yellow Brucite crystal cluster weighs approximately 261 carats / 52.2 grams and presents a vivid concentration of yellow Brucite crystals naturally developed on a contrasting metamorphic host rock.

Measuring approximately 57.0 × 49.0 × 18.3 mm, the specimen combines bright mineral colour with a broad, relatively low-profile matrix form, creating an attractive and highly decorative collector piece.

The Brucite displays a distinctive strong yellow colour, forming a concentrated crystal area across the host rock. The vivid coloration creates clear visual separation from the more neutral matrix and gives the specimen its principal aesthetic character.

Brucite is a naturally occurring magnesium hydroxide mineral, Mg(OH)₂, typically associated with magnesium-rich geological environments. It can form during metamorphic alteration of magnesium-rich rocks and is particularly associated with altered ultramafic rocks and serpentinite-related environments.

Bright yellow Brucite has become especially recognised among mineral collectors through notable specimens from Pakistan, where highly saturated yellow material has produced some of the most visually distinctive modern collector examples of the mineral.

The crystal growth is naturally concentrated across the central portion of the matrix, producing a pleasing balance between exposed yellow Brucite and the surrounding host rock. This arrangement preserves the geological relationship between mineral and matrix while maintaining strong decorative appeal.

The specimen remains in its natural, unpolished state, preserving original crystal surfaces, growth textures, matrix contacts and geological irregularities. Minor fissures, incomplete crystal edges, contact areas or small natural abrasions may occur and are normal characteristics of an unmodified mineral specimen.

Because natural rough mineral specimens have irregular shapes, the stated measurements are approximate and depend on the exact points selected during measurement. They are provided as a practical indication of the specimen’s overall dimensions.

Unique Piece: Natural individual formation

With its bright yellow Brucite crystals, attractive concentration of crystal growth and contrasting metamorphic matrix, this 261 ct specimen offers strong visual and geological character. Its natural formation and distinctive colour make it particularly suitable for a mineral collection, cabinet display or refined decorative presentation.
