Likely Non-Diamond (Potential Glass or Quartz Slug)
Likely Non-Diamond (Potential Glass or Quartz Slug) · Rough / Irregular Uncut Flat
N/A (Rough/Uncut state) Cut
Carat
Estimated 2.0 - 5.0 carats based on size relative to fingertip
Color
Estimated K-M (Faint Yellow/Tinted)
Clarity
I3 / Included (Heavily fractured/included)
Shape
Rough / Irregular Uncut Flat
Overall Assessment
The specimen lacks the adamantine luster and specific crystal habit expected of a natural diamond. It appears to be a fragment of high-lead glass or a common silicate mineral with heavy surface wear.
Cut Quality
N/A (Rough/Uncut state)
Brilliance
Very Low (Lacks internal reflection)
Fire
None detected
Scintillation
None detected
Proportions
Indeterminate (Lacks faceted geometry)
Symmetry
N/A (Asymmetric rough shape)
Polish
N/A (Original rough surface with conchoidal fracturing)
Fluorescence
Indeterminate from image
Inclusions
Large internal fractures, swirl marks, and potential air inclusions
Blemishes
External pitting, jagged edges, and surface abrasions
Origin
Terrestrial (Likely industrial byproduct or common silicate)
Treatment Detection
None apparent; appears as raw weathered debris
Estimated Value
Minimal to Nominal ($1 - $20 USD as a specimen)
Certification Estimate
Unlikely to receive a diamond grading report from GIA; potential GIA Identification Report for non-diamond material
Investment Potential
None
Similar Diamonds
Rough industrial bort or low-grade 'Boart' diamond
Setting Suggestions
Not recommended for jewelry setting without significant lapidary work
Care & Maintenance
Avoid impact; the specimen shows signs of brittleness and large cleavage planes
Interesting Facts
The conchoidal (shell-like) fracture patterns on the surface are more characteristic of glass or quartz than the octahedral cleavage of a diamond
