Natural rough mineral crystal (likely quartz, glass slag, or silica-based formation rather than a traditional gem-quality diamond)
Natural rough mineral crystal (likely quartz, glass slag, or silica-based formation rather than a traditional gem-quality diamond) · Rough, irregular elongated crystal formation / Untreated matrix
Not Applicable (Uncut, raw mineral specimen) Cut
Carat
Exceeds standard gem scale; estimated in excess of 100+ carats of raw mineral mass, though largely non-gem-grade
Color
Translucent to pale milky white with dark matrix inclusions
Clarity
I3 / Heavily included with extensive internal fractures, bubbles, and matrix matter
Shape
Rough, irregular elongated crystal formation / Untreated matrix
Overall Assessment
The specimen displayed is an interesting raw mineral or glassy formation, but it lacks the chemical composition, hardness, and crystal structure characteristic of a genuine diamond. It is best appreciated as an educational raw mineral sample.
Cut Quality
Not Applicable (Uncut, raw mineral specimen)
Brilliance
Low to moderate due to opaque matrix and lack of optical cut facets
Fire
Minimal to none due to absence of precise faceting and high internal inclusion count
Scintillation
Negligible, as light cannot effectively reflect and return through the raw structure
Proportions
Irregular raw specimen with no standard pavilion, table, or crown angles
Symmetry
Asymmetrical, natural raw growth habit
Polish
Unpolished, natural rough texture with glassy/resinous luster in patches
Fluorescence
Unknown without UV testing, likely Inert
Inclusions
Heavy internal fracturing, veil-like inclusions, and host rock matrix attachments
Blemishes
Rough surface pitting, natural irregularities, and adherent surface debris
Origin
Natural geological formation or potentially industrial/slag byproduct depending on exact mineral composition
Treatment Detection
None detected; appears entirely untreated and in its raw, natural state
Estimated Value
Nominal decorative mineral specimen value, primarily of educational or geological interest rather than commercial gemstone value
Certification Estimate
Not applicable for standard diamond grading laboratories; may be evaluated by a mineralogical institute for species identification
Investment Potential
Low; valuable strictly as a unique natural specimen or mineral curiosity rather than an investment asset
Similar Diamonds
None; this specimen exhibits characteristics closer to raw quartz, fulgurite, or slag glass than a crystalline diamond
Setting Suggestions
Wire-wrapped organic jewelry setting or display as a raw mineral specimen
Care & Maintenance
Handle with care to prevent chipping of fragile raw edges; clean gently with warm soapy water and a soft brush
Interesting Facts
Raw mineral specimens like this often get mistaken for precious gemstones by untrained observers due to translucent patches and vitreous luster
