Rough Aggregate Mineral Matrix (Likely Quartz/Calcite, not a single gem-quality diamond specimen)
Rough Aggregate Mineral Matrix (Likely Quartz/Calcite, not a single gem-quality diamond specimen) · Rough crystalline aggregate, unpolished matrix
Not applicable (Rough Uncut) Cut
Carat
Not applicable for rough matrix cluster
Color
Off-white to grayish with earthy matrix staining
Clarity
Included / Heavily Opaque
Shape
Rough crystalline aggregate, unpolished matrix
Overall Assessment
The provided image displays a rough, unprocessed mineral aggregate or cluster embedded in matrix rather than a cut, gem-grade diamond. Further testing (such as refractometer or thermal conductivity) is recommended to confirm exact mineral species.
Cut Quality
Not applicable (Rough Uncut)
Brilliance
Low due to opaque, rough, and unpolished crystal surfaces
Fire
Minimal dispersion visible on raw crystal faces
Scintillation
Low, limited sparkle due to lack of facet alignment
Proportions
Irregular raw crystal formations, no standard table or depth proportions
Symmetry
Asymmetrical natural crystal cluster formation
Polish
Unpolished, raw matrix state
Fluorescence
Indeterminate from visual image
Inclusions
Heavy internal fracturing, mineral inclusions, and matrix material
Blemishes
Surface pitting, natural rough crystal skin, and matrix adherence
Origin
Natural rough mineral deposit
Treatment Detection
No obvious signs of artificial treatments, appears entirely natural and untreated
Estimated Value
Nominal decorative mineral specimen value, not valued as faceted gem diamond
Certification Estimate
Standard gemological laboratories (GIA/AGS) typically do not grade rough mineral matrices of this type
Investment Potential
Low investment potential for jewelry use; strictly specimen/collector interest
Similar Diamonds
None, as this appears to be a mineral aggregate rather than diamond rough
Setting Suggestions
Display as a raw mineral specimen rather than a jewelry centerpiece
Care & Maintenance
Keep away from harsh chemicals; gentle dusting or mild soap solution for cleaning
Interesting Facts
Rough crystalline clusters often showcase the natural growth habit of minerals before human cutting and polishing
