Natural rough industrial/gem-grade diamond crystals - Uncut, raw crystal shapes (octahedral, macle, and irregular crystal fragments)

Carat

Estimated total strand weight between 15 to 25 carats (individual pieces ranging from ~0.10 to ~0.50 carats each)

Color

Fancy Brown to yellowish-brown (natural Earth-mined color)

Clarity

Included (rough material contains natural internal crystal feathers, clouds, and carbon spots)

Shape

Uncut, raw crystal shapes (octahedral, macle, and irregular crystal fragments)

Overall Assessment

A charming and unique strand of natural brown rough diamond crystals, highly favored in modern artisanal and organic jewelry design for their raw, earthy elegance

Cut Quality

Not applicable (rough, unpolished mineral specimens)

Brilliance

Low to moderate due to rough, unpolished surfaces absorbing and scattering light rather than internal refraction

Fire

Minimal due to absence of precision-cut facets

Scintillation

Limited, reflecting light off raw crystal faces rather than structured facets

Proportions

Natural uncut proportions with irregular depth and table equivalents

Symmetry

Natural crystal symmetry (organic, non-faceted growth forms)

Polish

Unpolished natural crystal faces (some may show natural trigons)

Fluorescence

Variable (typically inert to medium blue under UV light for natural brown rough)

Inclusions

Abundant natural mineral inclusions, feathers, and pinpoint clouds characteristic of rough stones

Blemishes

Natural surface textures, growth lines, and occasional chips from extraction

Origin

Likely alluvial or primary pipe deposits from African, Australian, or Canadian mines

Treatment Detection

No treatments detected; completely untreated natural rough diamonds

Estimated Value

Moderate market value, typically valued per carat for raw jewelry design or industrial collector specimens

Certification Estimate

Typically sold without individual grading reports; bulk gemological certificates or origin certificates from labs like GIA or IGI upon special request

Investment Potential

Niche market value; prized more for aesthetic and artisanal jewelry use rather than traditional diamond investment

Similar Diamonds

Other natural rough diamond strands, uncut diamond bead necklaces, and rustic slice jewelry

Setting Suggestions

Best suited for organic, rustic, or bohemian jewelry designs, such as bezel settings, wire-wrapping, or protective prong settings in yellow gold or platinum

Care & Maintenance

Clean with mild soapy water and a soft brush; avoid harsh ultrasonic cleaners due to potential natural fractures in raw stones

Interesting Facts

These diamonds represent the raw, unaltered state of nature before human cutting and polishing transformed the diamond industry
