Natural rough diamond or quartz crystal shard, requiring formal laboratory testing for absolute verification, though visual structure suggests a crystalline mineral fragment.
Natural rough diamond or quartz crystal shard, requiring formal laboratory testing for absolute verification, though visual structure suggests a crystalline mineral fragment. · Uncut, rough, irregular elongated crystal fragment with natural fracture surfaces.
Uncut / Rough specimen; standard cut grades do not apply. Cut
Carat
Estimated at 1.50 to 2.50 carats based on visual volume relative to human fingers.
Color
Near colorless to faint yellow (approximate G-I range if polished).
Clarity
Included (I1-I3 equivalent), showing visible internal fractures, feathering, and inclusions.
Shape
Uncut, rough, irregular elongated crystal fragment with natural fracture surfaces.
Overall Assessment
This specimen presents as a fascinating, natural raw crystalline shard with significant internal character. While it lacks the optical performance and clarity of a traditional cut gemstone, its raw, organic aesthetic holds unique appeal for collectors and custom jewelry designers.
Cut Quality
Uncut / Rough specimen; standard cut grades do not apply.
Brilliance
Low to moderate white light return due to raw, unpolished surfaces and internal fracturing.
Fire
Minimal spectral dispersion due to rough surface scattering and lack of precision-cut facets.
Scintillation
Poor scintillation; light is scattered unevenly across rough, fractured faces rather than reflected systematically.
Proportions
Non-standard proportions; raw uncut crystal form lacking traditional table, crown, and pavilion.
Symmetry
Natural asymmetrical rough formation with irregular growth patterns.
Polish
Unpolished natural crystal faces and fracture planes; rough texture.
Fluorescence
Indeterminate from visual inspection alone; typically requires UV light testing.
Inclusions
Multiple prominent internal fractures, feathers, and cloud-like mineral deposits visible throughout the structure.
Blemishes
Natural surface trigons, growth lines, chips, and irregular cleavage planes.
Origin
Likely alluvial or primary kimberlite pipe origin, typical of natural rough diamond mining regions (e.g., South Africa, Canada, Russia), or potentially quartz from a hydrothermal vein.
Treatment Detection
No visible evidence of artificial treatments (such as fracture filling or laser drilling), appearing entirely natural.
Estimated Value
Nominal value as a raw mineral specimen or collector piece, significantly lower than a faceted diamond of equivalent weight due to lower clarity and lack of standard cut.
Certification Estimate
Major grading laboratories (like GIA or IGI) would typically certify this only as an unmounted rough stone with a weight and dimensions report, rather than a standard cut grading report.
Investment Potential
Low investment liquidity as a cut diamond, but holds niche value for mineral collectors or bespoke jewelry designers.
Similar Diamonds
Comparable to industrial-grade or low-clarity natural diamond rough specimens sold to collectors and custom jewelry artisans.
Setting Suggestions
Best suited for organic wire-wrapped jewelry, custom raw-stone artisan settings, or preserved as a raw mineral specimen.
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal fractures.
Interesting Facts
Rough diamonds straight from the earth often look deceptively like ordinary glass or quartz until properly tested for thermal conductivity and hardness.
