This attractive natural Yellow Brucite crystal cluster weighs approximately 134.80 carats / 26.96 grams and features a concentrated development of bright yellow Brucite across a contrasting natural rock matrix.
Measuring approximately 48.3 × 31.5 × 18.6 mm, the specimen has a compact but visually expressive form, with the yellow Brucite forming the principal focal point of the cluster.
The Brucite displays a strong bright yellow to yellow colour, with individual crystal aggregates producing attractive reflective highlights across the surface. The concentration of yellow mineral growth against the darker and more neutral host rock creates strong natural contrast and gives the specimen considerable decorative appeal.
Brucite is a naturally occurring magnesium hydroxide mineral, Mg(OH)₂, typically formed in magnesium-rich geological environments. It is commonly associated with metamorphic alteration of ultramafic rocks and serpentinite-related deposits, and may also occur in certain hydrothermal environments.
Highly attractive yellow Brucite has gained particular attention among mineral collectors through important discoveries in Pakistan, where strongly coloured specimens have become recognised for their vivid yellow appearance. Yellow remains one of the most visually distinctive colour expressions of collector-quality Brucite.
The crystal development on this specimen is concentrated effectively across the matrix, allowing the yellow mineral growth to remain clearly visible while preserving sufficient host rock to provide geological context and structural contrast.
The specimen remains in its natural rough and unpolished condition. Original crystal surfaces, growth textures, matrix contacts and natural irregularities are preserved. Minor cleavage-related features, contact marks, edge irregularities or small fissures may occur and are normal characteristics of naturally formed Brucite.
Because natural rough mineral specimens have irregular shapes, the stated dimensions are approximate and depend on the selected measuring points. They are provided as a practical indication of the specimen’s overall size.
Unique Piece: Natural individual formation
With its bright yellow Brucite, compact proportions and strong contrast against the natural rock matrix, this 134.80 ct specimen offers an attractive combination of mineralogical interest and decorative character. Its concentrated crystal growth and vivid colour make it well suited to both a curated mineral collection and refined natural stone display.
