Natural Rough Crystal (Likely Quartz or Topaz, not Diamond)
Natural Rough Crystal (Likely Quartz or Topaz, not Diamond) · Uncut Rough / Irregular Macle-like shape
N/A (Rough/Raw state) Cut
Carat
Estimated 3.0 to 5.0 carats based on finger scale
Color
Near-Colorless with slight gray/brown undertone
Clarity
Included (I-grade equivalent if it were a diamond)
Shape
Uncut Rough / Irregular Macle-like shape
Overall Assessment
This specimen appears to be a natural mineral crystal, likely a silicate such as Quartz. It lacks the characteristic adamantine luster and geometric crystal habit of a high-value rough diamond.
Cut Quality
N/A (Rough/Raw state)
Brilliance
Low (Typical of uncut rough material)
Fire
Low to None visible in current state
Scintillation
Minimal surface reflection only
Proportions
Elongated prismatic form
Symmetry
N/A (Natural crystal asymmetry visible)
Polish
N/A (Natural crystal surface textures)
Fluorescence
Indeterminable without UV light
Inclusions
Visible internal fractures, reddish-pink mineral inclusions, and dark carbon/matrix spots
Blemishes
Surface pitting and natural growth striations
Origin
Alluvial or secondary deposit based on context
Treatment Detection
None apparent; looks to be in a natural raw state
Estimated Value
$10 - $50 (Assuming it is a common mineral specimen such as Quartz)
Certification Estimate
GIA (Rough Diamond Report) if confirmed as diamond; however, visual habit suggests a common silicate mineral
Investment Potential
Low; unlikely to yield a high-quality faceted stone
Similar Diamonds
Rough 'Industrial' grade bort or low-grade Macles
Setting Suggestions
Wire-wrapped pendant or custom 'rough cut' claw setting for organic jewelry
Care & Maintenance
Clean with warm soapy water and a soft brush; handle with care to avoid cleavage plane fractures
Interesting Facts
The elongated shape and visible internal pinkish grains are more characteristic of Topaz or Quartz than the typical octahedral habit of natural diamonds
