Not a diamond; appears to be raw quartz crystal or glass/slag
Not a diamond; appears to be raw quartz crystal or glass/slag · Rough uncut fragment / irregular piece
Not applicable (uncut rough material) Cut
Carat
Cannot be accurately determined from visual estimation alone, likely substantial due to physical size
Color
Colorless with some surface dirt/inclusions
Clarity
I3 / Included due to numerous internal inclusions, gas bubbles, or fractures
Shape
Rough uncut fragment / irregular piece
Overall Assessment
The specimen shown in the image lacks the characteristic crystal habit, high refractive index, and adamantine luster of a diamond, and is visually consistent with rough quartz or transparent glass.
Cut Quality
Not applicable (uncut rough material)
Brilliance
Low to moderate due to rough and irregular surface scattering light
Fire
Minimal
Scintillation
Poor due to lack of standard facets and symmetrical light return
Proportions
Not applicable
Symmetry
Not applicable (natural or irregular shape)
Polish
Unpolished raw surface
Fluorescence
Cannot be determined without UV testing
Inclusions
Heavy internal particulate matter and fractures
Blemishes
Surface chips, uneven texture, and potential casting/molding marks if glass
Origin
Natural mineral or manufactured glass object
Treatment Detection
None apparent, standard raw state
Estimated Value
Minimal monetary value (negligible)
Certification Estimate
Gemological laboratories would not issue a diamond certificate for this material
Investment Potential
None as a gemstone or investment asset
Similar Diamonds
None, as this is visually identified as quartz or glass rather than diamond
Setting Suggestions
Not suitable for standard jewelry settings unless tumbled or wire-wrapped as raw mineral specimen
Care & Maintenance
Standard cleaning with warm soapy water if quartz, handle carefully to avoid scratching softer materials
Interesting Facts
Many transparent rough minerals resemble diamonds to the untrained eye, but simple hardness testing (Mohs scale) easily differentiates them
