Not Diamond (Mineral Crystals / Quartz or Salt/Gypsum on Matrix)
Not Diamond (Mineral Crystals / Quartz or Salt/Gypsum on Matrix) · Rough / Uncut Microcrystalline or Drusy aggregate
Not Applicable (Rough, unpolished mineral formation) Cut
Carat
Not applicable for rough aggregate in matrix
Color
Colorless to Off-White / Translucent
Clarity
Included (Contains numerous internal crystal boundaries and matrix inclusions)
Shape
Rough / Uncut Microcrystalline or Drusy aggregate
Overall Assessment
The specimen displayed is a natural rock matrix covered in small mineral crystals (likely quartz, calcite, or salt crust), not rough diamonds. Professional testing (such as thermal conductivity or Raman spectroscopy) would confirm the non-diamond composition.
Cut Quality
Not Applicable (Rough, unpolished mineral formation)
Brilliance
Low to Moderate (limited by rough crystal surfaces and lack of facets)
Fire
Minimal dispersion observed
Scintillation
Scattered micro-reflections due to drusy surface texture
Proportions
Not Applicable
Symmetry
Natural crystalline formation, irregular
Polish
Unpolished, natural crystal faces and matrix interface
Fluorescence
Unknown / Not testable visually
Inclusions
Heavy natural mineral matrix inclusions and internal fracturing
Blemishes
Surface roughness, pitting, and matrix adherence
Origin
Natural geological formation (matrix rock with secondary crystal growth)
Treatment Detection
No treatments detected; natural specimen
Estimated Value
Minimal monetary value as gemstone material; specimen value only
Certification Estimate
Not eligible for standard diamond grading (GIA/AGS would issue mineral identification report)
Investment Potential
None as a diamond; low as a generic mineral specimen
Similar Diamonds
None (this specimen does not consist of gem-grade diamond)
Setting Suggestions
Not suitable for jewelry setting in current state; must be kept as a mineral specimen
Care & Maintenance
Keep dry, avoid harsh impacts that could fracture the delicate crystal crust on the matrix
