Natural (Uncut / Rough Diamonds)
Natural (Uncut / Rough Diamonds) · Rough / Raw Crystalline (Octahedral and Macle forms)
Not Applicable (Uncut rough stones) Cut
Carat
Estimated total weight of the strand: 20-30 carats (individual stones range from 0.10 to 1.5 carats)
Color
Fancy Brown to Light Yellowish-Brown (Industrial to Lower Commercial Grade)
Clarity
Included (I1-I3 equivalent due to internal clouds, feathers, and carbon spots)
Shape
Rough / Raw Crystalline (Octahedral and Macle forms)
Overall Assessment
An intriguing strand of natural, uncut brownish rough diamonds displaying authentic geological crystal forms, ideal for organic, artisanal, or rustic jewelry creations rather than traditional high-end luxury sparkle
Cut Quality
Not Applicable (Uncut rough stones)
Brilliance
Low to Moderate due to lack of facets and opaque/translucent rough nature
Fire
Minimal to none due to lack of facet dispersion
Scintillation
Limited, reflecting light off natural crystal faces rather than internal facets
Proportions
Natural rough geometry; no standard table, depth, crown, or pavilion angles
Symmetry
Natural crystalline symmetry (Asymmetrical rough forms)
Polish
Natural crystal faces (Unpolished)
Fluorescence
Variable (Typically None to Medium Yellow/Blue under UV)
Inclusions
Abundant natural mineral inclusions, clouds, feathers, and dark carbon spots visible throughout
Blemishes
Natural surface textures, trigons, etch channels, and rough skin
Origin
Likely alluvial or primary pipe deposits from Africa (e.g., DR Congo, South Africa) or Australia
Treatment Detection
No treatments detected; natural untreated rough condition
Estimated Value
$500 - $1,500 USD for the entire strand depending on total weight and durability
Certification Estimate
Typically sold via weight parcel without individual lab grading (GIA or local gemological institutes can issue rough diamond origin reports if requested)
Investment Potential
Low investment potential; primarily valued for artisanal and rustic jewelry design rather than store of wealth
Similar Diamonds
Industrial or low-grade jewelry-grade rough diamond parcels and uncut diamond bead necklaces
Setting Suggestions
Bezel settings, wire-wrapping, or organic jewelry designs utilizing raw uncut diamond aesthetics in yellow gold or platinum
Care & Maintenance
Clean with mild soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners to protect the strung cord and natural surface textures
Interesting Facts
Rough diamonds showcase the natural, unblemished geometric beauty of crystal growth straight from the Earth before human cutting and polishing
