Natural
Natural · Rough crystal / Natural octahedral or irregular crystal form
Uncut / Rough crystal stone Cut
Carat
Cannot be accurately determined from a microscopic internal inclusion or close-up macro view; requires scale weighing.
Color
Brownish-yellow bodycolor with natural staining
Clarity
Included (Contains visible feathers, fractures, and dark mineral inclusions at magnification)
Shape
Rough crystal / Natural octahedral or irregular crystal form
Overall Assessment
This is a fascinating macro or microscopic view of a natural rough diamond showing internal stress fractures, inclusions, and growth features, highlighting the raw and unaltered state of natural diamond formation
Cut Quality
Uncut / Rough crystal stone
Brilliance
Low to moderate due to rough surfaces and internal fracture planes diffusing light
Fire
Present along cleavage and fracture planes, though muted by rough exterior
Scintillation
Limited, dependent on internal reflections from fractures and crystal faces
Proportions
Natural crystal habit with distorted angles, no standard cut proportions apply
Symmetry
Natural crystal symmetry, distorted growth features visible
Polish
Raw, unpolished natural crystal surfaces and internal fracture planes
Fluorescence
Cannot be determined without UV light testing (typically medium to strong blue in natural rough brown diamonds, but unverified)
Inclusions
Large feather fracture, internal tension cracks, and dark or metallic inclusions
Blemishes
Natural surface trigons, rough skin, etching features, and irregular growth lines
Origin
Alluvial or primary kimberlite pipe deposit (Africa, Canada, or Australia are common sources for fancy colored rough)
Treatment Detection
No signs of artificial treatment; natural rough crystal features are prominent
Estimated Value
Varies widely based on total carat weight of the rough stone, cutting yield potential, and rarity of color
Certification Estimate
GIA or similar major lab, typically graded as Natural Diamond Rough with specific inclusion mapping
Investment Potential
Moderate; value is driven by whether the stone is cut and polished for maximum retention or sold as a collector's specimen
Similar Diamonds
Other natural fancy brown or yellow uncut diamond crystals used in rustic or avant-garde jewelry
Setting Suggestions
Can be set raw in organic, artisanal, or bespoke 'rough diamond' jewelry using bezel or prong settings
Care & Maintenance
Standard ultrasonic cleaning should be avoided due to large internal feathers and fractures; warm soapy water and a soft brush are safest
