Natural rough mineral matrix, likely calcite or quartz crystals, not a cut faceted diamond
Natural rough mineral matrix, likely calcite or quartz crystals, not a cut faceted diamond · Natural crystal habit, untutored rough mineral formation
Not applicable (Rough mineral specimen) Cut
Carat
Not applicable to rough mineral cluster matrix
Color
Off-white / translucent with matrix staining
Clarity
Included / Heavily included with internal fractures and mineral deposits
Shape
Natural crystal habit, untutored rough mineral formation
Overall Assessment
An interesting natural mineral crystal formation embedded in matrix, suitable for mineral collectors rather than jewelry use
Cut Quality
Not applicable (Rough mineral specimen)
Brilliance
Vitreous to sub-adamantine luster on natural crystal faces
Fire
Low dispersion typical of raw crystal formations
Scintillation
Limited flash effect from uneven natural crystal planes
Proportions
Natural crystal dimensions, no standard facet proportions
Symmetry
Natural asymmetric crystal growth
Polish
Natural unpolished crystal faces
Fluorescence
Cannot be determined without UV testing
Inclusions
Abundant internal fractures, mineral inclusions, and surface staining
Blemishes
Natural surface etching, fractures, and matrix attachments
Origin
Natural geological formation within a mineral vein or matrix
Treatment Detection
None detected; appears entirely natural and untreated
Estimated Value
Nominal value as a mineral specimen, highly dependent on the exact host rock and mineral species identification
Certification Estimate
Specimens like this are typically sold with mineralogical certificates rather than diamond grading reports (e.g., GIA Gemological identification report for minerals)
Investment Potential
Collected primarily for mineralogical, educational, or decorative purposes rather than financial investment
Similar Diamonds
Not comparable to standard polished or cut diamonds; similar to raw mineral crystal clusters
Setting Suggestions
Wire-wrapped in sterling silver or displayed raw in a mineral collection cabinet
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and physical impacts that could damage the fragile crystal matrix
Interesting Facts
Displays raw crystallization patterns directly from the earth before human cutting and polishing processes
