1.58 Ct. Brownish Green Andalusite

This specimen is a transparent 1.58 carat radiant shape andalusite, precisely measured at 11.29 x 5.06 x 3.09 mm, presenting a brownish green body color with medium color intensity. The cutting style is faceted, executed in the radiant cut manner that marries trimmed corners with a mixed facet schema to deliver both scintillation and color retention. The cutter oriented the pavilion and crown facets intentionally to respect the crystal symmetry, preserving strong pleochroic character while maximizing light return through the table. Facet junctions are sharp, crown facets exhibit consistent angles across the outline, and the girdle presents a uniform thickness that aids predictable setting behavior. Clarity is graded as eye clean, evaluated at eye level, which means the stone shows no inclusions visible without magnification, and the excellent polish produces crisp facet reflections with minimal surface disturbance. Enhancement status is none, this is a natural, unenhanced andalusite, and the origin is recorded as unknown in our inventory.

Optically this andalusite demonstrates the species typical strong pleochroism, with different orientations yielding discernible brown, green, and warmer tones, and the radiant faceting has been planned to showcase that trichroic response when the gem is rotated or when light direction changes. The cutter chose an elongated table and a relatively shallow profile to emphasize the brownish green interplay across the crown, while careful pavilion angling preserves lively scintillation without creating windowing or dead areas. The result is a gem whose color reading appears stable when set face up, yet offers engaging color shifts at oblique angles, a desirable attribute for collectors and designers who prize personality as much as color grade. Precision in facet symmetry and the excellent polish are evident under loupe magnification, and because there has been no enhancement applied, the observed color and clarity are entirely natural characteristics of the rough and of the cutter s orientation decisions.

From an ethical sourcing perspective The Natural Gemstone Company maintains rigorous procurement standards, and although the precise geographic origin of this particular andalusite is unknown, we track provenance as far as possible and engage only with suppliers who adhere to fair labor practices and environmental stewardship. We request documentation of chain of custody for every parcel we handle, perform periodic supplier audits, and prefer artisanal mining partnerships where traceability and community benefit are demonstrable. For the conscious collector this stone represents an uncompromised option, untreated and field honest, compatible with a collection assembled for ethical integrity as well as aesthetic distinction. Its robust facet work and natural pleochroism make it suitable for bespoke settings that highlight changing color, such as pendants and earrings where rotation is encouraged, or secure bezel and protective prong settings for rings to balance visibility with wearability. The Natural Gemstone Company stands ready to provide additional gemological imaging, independent lab testing upon request, and bespoke mounting consultation to ensure this andalusite integrates into a thoughtful, responsibly curated collection.
