Not a diamond; appears to be manufactured glass, slag glass, or quartz crystal with conchoidal fracturing.
Not a diamond; appears to be manufactured glass, slag glass, or quartz crystal with conchoidal fracturing. · Irregular raw fragment / amorphous piece
Not applicable; raw or fractured material rather than a faceted gem Cut
Carat
Cannot be accurately determined by visual assessment alone, roughly 10-15 carats equivalent volume
Color
Light purple / lavender tint
Clarity
Included / Heavily flawed due to internal bubbles and stress fractures
Shape
Irregular raw fragment / amorphous piece
Overall Assessment
The specimen presented is not a diamond. Based on the visible air bubbles and conchoidal fracture patterns, it is most likely a piece of colored glass, slag glass, or low-grade quartz. It lacks the hardness, optical properties, and crystal structure of a genuine diamond.
Cut Quality
Not applicable; raw or fractured material rather than a faceted gem
Brilliance
Low to moderate due to lack of proper faceting and internal impurities
Fire
Very low dispersion compared to diamond
Scintillation
Poor, lacks standard facets required for dynamic sparkle
Proportions
Not applicable
Symmetry
Poor / Asymmetrical
Polish
Rough / Unpolished fracture surfaces
Fluorescence
Unknown without UV testing, likely inert
Inclusions
Numerous gas bubbles, swirls, and internal stress fractures visible
Blemishes
Surface chips, rough edges, and uneven cleavage planes
Origin
Synthetic / Industrial glass or natural quartz pebble
Treatment Detection
Shows typical characteristics of melted/formed glass (trapped air bubbles), no gemological enhancements detected
Estimated Value
Minimal to negligible commercial value (decorative or novelty item only)
Certification Estimate
Will not be certified by major gemological laboratories (GIA, AGS, IGI) as it is not a diamond or precious gemstone
Investment Potential
None; holds zero financial investment value
Similar Diamonds
None, as this material is fundamentally distinct from diamond in chemical composition and physical properties
Setting Suggestions
Not recommended for fine jewelry settings due to softness and fragile fracture structure; wire-wrapping might suit it for craft purposes
Care & Maintenance
Handle with care to avoid cutting fingers on sharp fractured edges; clean with mild soapy water
Interesting Facts
The conchoidal fracture patterns closely mimic natural quartz or obsidian, which often leads to misidentification by untrained observers
