Not a diamond (Raw/Uncut Quartz or Quartzite) · Rough / Natural unpolished nugget
Uncut / Natural Cut
Carat
Not applicable as it is quartz, estimated mass visually exceeds standard gem-scale weights
Color
White to milky with brownish iron oxide staining
Clarity
Included / Opaque (Typical for rough quartz rock)
Shape
Rough / Natural unpolished nugget
Overall Assessment
The specimen pictured is a piece of rough, unpolished quartz or quartzite containing iron oxide staining within its fractures, entirely distinct from a diamond both chemically and physically.
Cut Quality
Uncut / Natural
Brilliance
Low due to lack of faceting and opaque crystalline structure
Fire
None
Scintillation
Minimal to none
Proportions
Irregular natural form with no standard facet proportions
Symmetry
Asymmetrical rough stone
Polish
Raw unpolished surface
Fluorescence
Indeterminate from visual inspection
Inclusions
Heavy internal fractures, granular textures, and mineral staining
Blemishes
Natural surface pits, roughness, and iron staining
Origin
Alluvial or primary vein quartz, ubiquitous globally
Treatment Detection
No treatments detected; natural stone in rough state
Estimated Value
Minimal (Decorative or specimen mineral value, less than $10 USD)
Certification Estimate
Standard gemological laboratories do not certify common quartz as a gemstone unless it is a notable variety (e.g., amethyst, ametrine)
Investment Potential
None as an investment; collectible mineral specimen only
Similar Diamonds
None, as this is quartz, not diamond
Setting Suggestions
Wire-wrapped rough stone pendant or rustic bezel setting
Care & Maintenance
Wash with mild soapy water and a soft brush; avoid harsh chemicals
