Synthetic Material / Glass (Not a Diamond)
Synthetic Material / Glass (Not a Diamond) · Rough / Uncut (Amorphous)
N/A (Rough state) Cut
Carat
Estimated 30-50 carats (based on size relative to matrix)
Color
Vivid Deep Blue (Cobalt intensity)
Clarity
Translucent to Opaque
Shape
Rough / Uncut (Amorphous)
Overall Assessment
This specimen is not a diamond. It is a piece of blue glass or industrial slag. It lacks the crystalline structure, adamantine luster, and refractive properties of a gemstone.
Cut Quality
N/A (Rough state)
Brilliance
Very Low (Surface reflection only)
Fire
None
Scintillation
None
Proportions
N/A (Asymmetric shard)
Symmetry
Poor (Irregular rough)
Polish
N/A (Natural/Fractured surface)
Fluorescence
None observed (Requires UV light for verification)
Inclusions
Bubbles and swirl marks (striae) typical of glass; conchoidal fractures
Blemishes
Heavy surface scratching and impact abrasions
Origin
Industrial byproduct (Cullet or Slag glass)
Treatment Detection
Man-made composition; cobalt or copper coloring agents
Estimated Value
$1 - $20 USD (Decorative/Curiosity value)
Certification Estimate
Not certifiable as a diamond; GIA/IGI would likely identify as Man-made Glass or Slag
Investment Potential
Zero investment value
Similar Diamonds
None (No natural diamond exhibits this specific conchoidal fracture and cobalt color saturation)
Setting Suggestions
Wire wrapping for decorative/novelty jewelry
Care & Maintenance
Avoid high heat and impacts; material is brittle and prone to shattering
Interesting Facts
The conchoidal (shell-like) fracture pattern and deep blue hue are classic indicators of man-made glass, frequently mistaken for rare gemstones in outdoor settings.
