Overall Assessment
An interesting and genuine natural rough diamond crystal displaying classic growth lines and internal characteristics, ideal either for collector display or custom cutting.
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Low in rough form; will exhibit brilliance once cut and polished
Fire
Minimal dispersion in rough state; expected standard fire once faceted
Scintillation
Limited flash effect due to rough, unpolished surface facets
Proportions
Natural rough proportions, requires professional cutter planning
Symmetry
Natural crystal symmetry (distorted octahedral/dodecahedral)
Polish
Natural unpolished crystal faces with typical trigons or growth striations
Fluorescence
Unknown (requires UV testing)
Inclusions
Internal cloud formations, pinpoint clusters, and potential feather inclusions typical of natural rough
Blemishes
Natural surface etch channels, growth marks, and surface graining
Origin
Natural primary alluvial or kimberlitic deposit (exact mine origin unknown without advanced spectroscopy)
Treatment Detection
No indications of artificial treatment; untreated natural rough
Estimated Value
Varies widely depending on cutting yield and final polished grade; rough value typically ranges from hundreds to thousands of dollars
Certification Estimate
GIA or IGI rough diamond report or full grading post-cutting
Investment Potential
Moderate to high speculative potential depending on cutting retention and final polished clarity
Similar Diamonds
Comparable to standard run-of-mine gem-quality natural rough crystals
Setting Suggestions
Can be set in a custom raw-diamond bezel or prong setting, or planned for a brilliant-cut modern engagement ring
Care & Maintenance
Store separately to prevent scratching other jewelry; clean with mild soapy water and a soft brush
