This remarkable natural mineral specimen features a group of green Emerald crystals naturally developed on a contrasting Feldspar matrix, creating an impressive three-dimensional collector formation.
Recorded as originating from the Panjshir Valley, Afghanistan, the specimen weighs approximately 572.95 carats / 114.59 grams and measures around 63.0 × 49.9 × 40.6 mm.
Emerald is the green gem variety of Beryl, with the chemical composition Be₃Al₂Si₆O₁₈. Its green coloration is principally associated with trace amounts of chromium and/or vanadium, although the precise chromophore chemistry of an individual specimen requires analytical confirmation.
The Emerald crystals display an attractive medium to vivid green colour, standing out clearly against the pale Feldspar host rock. Several crystals occur together across the matrix, creating a naturally clustered formation with strong colour contrast and considerable visual depth.
A particularly attractive feature of this specimen is the presence of well-developed crystal faces and visible natural terminations. The crystals retain their original growth morphology and show the characteristic prismatic structure associated with Beryl.
The Feldspar matrix provides an effective pale background for the green Emerald and preserves the geological relationship between the crystals and their host material. Natural cavities, matrix contacts, growth irregularities and associated mineral features remain visible throughout the specimen.
As a natural collector specimen, the Emerald crystals may display internal inclusions, growth zoning, fine fissures, surface-reaching features and minor contact-related irregularities. These characteristics are consistent with natural Emerald formation and contribute to the geological individuality of the piece.
The specimen remains in its natural, unpolished condition, without artificial shaping. Its substantial size, strong Emerald-to-matrix contrast and multi-crystal development make it particularly suitable for a mineral cabinet, geological collection or premium natural specimen display.
Because natural mineral specimens have irregular forms, the stated dimensions are approximate and depend on the precise points selected during measurement. They are provided as a practical indication of the overall specimen size.
Unique Piece: Natural individual formation
With its well-developed green Emerald crystals, visible natural terminations, pale Feldspar matrix and strong overall balance, this 572.95 ct specimen presents an impressive example of Emerald preserved within its natural geological setting. Its recorded Panjshir Valley provenance and substantial three-dimensional crystal formation add further collector interest.
