Not applicable (Unfaceted, tumbled or broken shard) Cut

Carat
Not applicable (glass material; estimated visual weight would be non-standard)
Color
Vivid Blue (Fancy Blue simulation, though derived from glass)
Clarity
Not applicable (Contains numerous gas bubbles and surface pitting, typical of glass)
Shape
Irregular / Tumbled (Not a faceted diamond shape)
Overall Assessment
The item in the image is a piece of frosted blue glass (likely sea glass), not a diamond or precious gemstone. It features characteristic air bubbles and a tumbled texture entirely distinct from crystalline diamond structure.
Cut Quality
Not applicable (Unfaceted, tumbled or broken shard)
Brilliance
Low to moderate due to frosted surface and lack of facets
Fire
None (Glass lacks the high refractive index and dispersion of diamond)
Scintillation
None (No facets to reflect light dynamically)
Proportions
Irregular shard proportions
Symmetry
Asymmetrical (Natural or tumbled erosion)
Polish
Matte / Frosted (Typical of sea glass tumbled in sand and water)
Fluorescence
Cannot be definitively determined without UV testing, though glowing strongly under direct backlight
Inclusions
Numerous spherical gas bubbles and internal impurities visible
Blemishes
Surface pitting, abrasion marks, and frosted texture from tumbling
Origin
Man-made glass fragment (likely discarded bottle or container glass smoothed by natural wave action or tumbling)
Treatment Detection
Colored glass manufactured with cobalt or other colorants
Estimated Value
Nominal / Collector value only (typically valued as craft or beach-combing sea glass, under $5)
Certification Estimate
Cannot be certified by major diamond grading labs (GIA, IGI, etc.) as it is not a diamond or gemstone
Investment Potential
None as a gemstone or diamond asset
Similar Diamonds
None (completely different mineral and material composition)
Setting Suggestions
Wire-wrapped in sterling silver or gold-filled wire for casual artisanal jewelry
Care & Maintenance
Wash with mild soap and warm water; avoid harsh chemicals
Interesting Facts
Bright blue sea glass is relatively rare compared to green or brown, often originating from old medicine bottles, apothecary jars, or decorative glassware.
