Natural rough diamond crystal
Natural rough diamond crystal · Rough octahedral/irregular crystalline form, unpolished
Not applicable (Rough uncut stone) Cut
Carat
Estimated 3.5 - 5.0 carats
Color
Near-colorless to light brown tint (approx. K-M equivalent)
Clarity
Included (I1-I2)
Shape
Rough octahedral/irregular crystalline form, unpolished
Overall Assessment
This is a raw, untreated natural diamond crystal exhibiting significant internal inclusions and natural surface features, ideal as a mineral specimen or for specialized raw jewelry designs.
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low to moderate due to rough surfaces and internal inclusions
Fire
Minimal dispersion visible through raw, unfaceted surfaces
Scintillation
Limited flash effect due to lack of standard pavilion and crown facets
Proportions
Natural rough crystal proportions, not cut to standard optical angles
Symmetry
Natural asymmetrical rough growth
Polish
Raw, unpolished natural crystal faces and fracture surfaces
Fluorescence
Cannot be determined without UV testing (likely Faint to Medium)
Inclusions
Heavy internal clouding, mineral crystals, dark pinpoint inclusions, and internal feathers
Blemishes
Natural surface etch channels, trigons, rough skin, and conchoidal fracture marks
Origin
Likely alluvial deposit or primary kimberlite pipe origin (e.g., Africa, Canada, or Russia)
Treatment Detection
No signs of enhancement; completely untreated natural rough specimen
Estimated Value
$300 - $800 depending on final yield if cut, or specimen value
Certification Estimate
GIA or EGL would grade it as a rough industrial or low-gem quality crystal
Investment Potential
Low as a polished gem investment; moderate as a mineral specimen or collectible curiosity
Similar Diamonds
Comparable industrial and low-clarity gem-quality rough diamond crystals
Setting Suggestions
Organic raw crystal pendant setting using yellow or rose gold wire-wrap
Care & Maintenance
Standard cleaning with warm soapy water and a soft brush; avoid harsh acids or impacts that could propagate internal fractures
