Rough Natural Diamond Crystal
Rough Natural Diamond Crystal · Rough Crystal / Uncut Octahedral/Irregular Fragment
Not Applicable (Uncut Rough Specimen) Cut

Carat
Estimated 2.0 to 3.5 carats based on visual proportions
Color
Near-Colorless to Light Brownish/Gray tint (approx. G-J range)
Clarity
Included (I1-I3 range) with heavy internal feathering, cloud formations, and crystal inclusions
Shape
Rough Crystal / Uncut Octahedral/Irregular Fragment
Overall Assessment
This is a fascinating specimen of a natural rough diamond crystal showcasing raw geological features, growth striations, and internal character, offering great potential for custom organic jewelry or mineral collection
Cut Quality
Not Applicable (Uncut Rough Specimen)
Brilliance
Limited due to rough surface and heavy internal inclusions; highly dependent on future cutting and polishing
Fire
Minimal in current rough state; requires proper pavilion and crown faceting to exhibit dispersion
Scintillation
Absent in current uncut form
Proportions
Natural rough form with distinct growth lines, natural etching, and irregular surface texture
Symmetry
Natural asymmetric crystal growth features including striations (trigons/growth lines)
Polish
Natural crystalline faces (octahedral faces with characteristic frosted or pitted texture)
Fluorescence
Indeterminate from visual assessment alone; likely None to Moderate Blue under UV
Inclusions
Abundant internal strain lines, feather fractures, needle-like inclusions, and cloud zones
Blemishes
Natural surface pitting, rough skin, and irregular crystal edges
Origin
Natural geological origin from a primary kimberlite pipe or secondary alluvial deposit
Treatment Detection
No treatments detected; completely untreated natural rough mineral state
Estimated Value
Ranges significantly as a mineral specimen ($500 - $2,000 depending on industrial vs. collector market)
Certification Estimate
GIA or IGI would classify this as an uncertified rough diamond specimen
Investment Potential
Moderate value primarily as a unique mineral specimen or raw jewelry piece rather than liquid investment diamond
Similar Diamonds
Comparable to industrial or lower-gem-grade natural rough diamond octahedrons and crystal fragments
Setting Suggestions
Best displayed in a bespoke raw-stone jewelry setting using protective prongs or bezel in 14k/18k yellow or white gold
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal feather fractures
Interesting Facts
The visible growth lines and striations on the surface are geological fingerprints showing how the carbon atoms crystallized deep within the Earth's mantle under extreme pressure and temperature
