Overall Assessment
This specimen is not a diamond or a precious gemstone. Visual characteristics including conchoidal fracture patterns and greenish-grey coloration strongly indicate colored glass, industrial slag, or a common non-gem mineral.
Cut Quality
Not Applicable (Uncut rough fragment)
Brilliance
Low to none due to lack of standard facet alignment and material properties
Fire
Minimal to none
Scintillation
Poor, lacks standard reflective facets
Proportions
Not Applicable
Symmetry
Not Applicable
Polish
Unpolished
Fluorescence
Unknown (Requires UV testing)
Inclusions
Heavy internal fractures, bubbles, or structural impurities typical of glass or slag
Blemishes
Surface pitting, conchoidal fracture lines, and weathering marks
Origin
Synthetic industrial waste or terrestrial mineral fragment
Treatment Detection
Likely untreated, though potentially colored via artificial additives if glass/slag
Estimated Value
Minimal (Decorative or specimen value only, essentially negligible commercial gemstone value)
Certification Estimate
Not certifiable as a gemstone by major labs (GIA, AGS, IGI)
Investment Potential
None
Similar Diamonds
None (No gemological similarity to diamond)
Setting Suggestions
Not recommended for fine jewelry due to softness and material composition
Care & Maintenance
Store separately to avoid scratching softer materials, clean with mild soapy water
Interesting Facts
Materials resembling this are often found near historical industrial sites or beaches as sea glass
