Not a diamond; appears to be quartz, glass, or a synthetic imitation material based on the conchoidal fracture and surface luster.
Not a diamond; appears to be quartz, glass, or a synthetic imitation material based on the conchoidal fracture and surface luster. · Irregular raw crystal fragment / Uncut rough shard
Poor / Uncut / Raw Cut
Carat
Cannot be accurately determined from a microscopic/macro view without dimension measurements, but visually a small fragment under 1 carat equivalent.
Color
Colorless (transparent)
Clarity
Included / Imperfect due to internal fractures, swirl patterns, and inclusions.
Shape
Irregular raw crystal fragment / Uncut rough shard
Overall Assessment
Based on visual characteristics including surface luster, fracture patterns, and internal structure, this item is not a diamond. It is a crystalline mineral fragment (likely quartz) or glass shard requiring professional physical testing for exact identification.
Cut Quality
Poor / Uncut / Raw
Brilliance
Low to moderate, lacking the high refractive index and dispersion of a true diamond
Fire
Minimal dispersion compared to diamond or moissanite
Scintillation
Poor due to lack of facet arrangement
Proportions
Non-standard, irregular fragment lacking traditional diamond facets or proportions
Symmetry
Asymmetrical, irregular natural or broken form
Polish
Raw/unpolished fracture surfaces with some vitreous luster
Fluorescence
Indeterminate visually
Inclusions
Internal stress fractures, bubbles, or fluid/gas inclusions characteristic of non-diamond crystalline material or glass
Blemishes
Surface chips, natural growth lines, and concoidal fracture marks
Origin
Natural quartz crystal or synthetic glass fragment
Treatment Detection
No obvious artificial enhancements detected, but material requires advanced spectroscopic testing.
Estimated Value
Minimal nominal value as a gemstone; primarily of specimen or decorative interest only.
Certification Estimate
Standard gemological laboratories (GIA, AGS, etc.) would issue a gemstone identification report rather than a diamond grading report, likely identifying it as quartz or glass.
Investment Potential
None; this specimen holds no financial investment value.
Similar Diamonds
None, as this material lacks gemstone-quality diamond properties.
Setting Suggestions
Not recommended for fine jewelry settings due to durability and material identity.
Care & Maintenance
Store separately to prevent scratching softer materials, clean with mild soapy water and a soft brush.
Interesting Facts
Conchoidal fractures like the one visible on this specimen are characteristic of amorphous materials like glass or crypto-crystalline quartz rather than the octahedral cleavage of diamond.
