Natural rough or heavily included crystal, likely industrial or low-grade gem quality with dense cloud/inclusion patterns
Natural rough or heavily included crystal, likely industrial or low-grade gem quality with dense cloud/inclusion patterns · Rectangular / Cushion rough crystal
Poor (Uncut rough or very poorly shaped preform) Cut

Carat
Estimated 2.0 - 3.5 carats based on visual scale
Color
Light blue or greenish-blue tint due to inclusions/nature, difficult to grade strictly on D-Z scale
Clarity
I3 (Included 3) with dense clouds, pinpoints, and heavy internal features
Shape
Rectangular / Cushion rough crystal
Overall Assessment
This is a low-clarity, heavily included natural diamond crystal in a rough, unpolished state, best suited as a mineral specimen rather than a faceted gemstone.
Cut Quality
Poor (Uncut rough or very poorly shaped preform)
Brilliance
Very low due to opacity and dense inclusions diffusing light
Fire
Negligible due to lack of standard faceted proportions and high opacity
Scintillation
Minimal, light is scattered internally rather than returned to the eye
Proportions
Non-standard rough geometry, deep pavilion, unpolished table
Symmetry
Poor (Asymmetrical rough form)
Polish
Poor (Unpolished rough surface with natural textures)
Fluorescence
Indeterminate from visual alone, requires UV testing
Inclusions
Dense internal cloudiness, pinpoints, feather clusters throughout the volume
Blemishes
Natural surface trigons, roughness, pitting, and uneven growth marks
Origin
Natural rough diamond, potential alluvial or primary pipe origin
Treatment Detection
No obvious signs of artificial treatments, appears as-mined rough
Estimated Value
Nominal value, primarily industrial or low-grade specimen value
Certification Estimate
Not economically viable for major grading labs like GIA or AGS due to low clarity grade
Investment Potential
Very low; primarily a mineral specimen rather than an investment asset
Similar Diamonds
Low-grade industrial boart or heavily included near-gem rough
Setting Suggestions
Not recommended for fine jewelry settings in current state; requires professional cutting and polishing
Care & Maintenance
Standard handling for mineral specimens; avoid harsh acids or impact
Interesting Facts
Demonstrates heavy internal inclusion patterns common in natural diamond growth under high pressure and temperature
