Overall Assessment
The specimen shown in the image is a raw crystalline mineral (likely quartz) rather than a diamond, displaying natural striations and surface irregularities typical of rough gemstone crystals.
Cut Quality
Uncut / Raw crystal
Brilliance
Low, due to lack of faceting and surface wear
Fire
None, characteristic of quartz rather than diamond
Scintillation
Poor, unfaceted raw surface
Proportions
Natural crystal habit proportions
Symmetry
Natural crystal symmetry
Polish
Rough, unpolished natural faces
Fluorescence
Cannot be determined visually without UV testing
Inclusions
Abundant internal fractures, feathering, and mineral inclusions
Blemishes
Natural surface etching, striations, and minor chips
Origin
Natural terrestrial mineral deposit
Treatment Detection
No obvious signs of artificial treatment; natural weathering evident
Estimated Value
Nominal mineral specimen value (less than $50)
Certification Estimate
N/A for rough quartz specimens; gemological lab would issue identification report rather than diamond grading
Investment Potential
Low; valuable only as a mineral specimen for collectors
Similar Diamonds
None (this is not a diamond)
Setting Suggestions
Wire-wrapped or organic bezel settings for raw mineral jewelry
Care & Maintenance
Clean gently with warm soapy water; avoid harsh impacts due to natural fractures
Interesting Facts
