Natural rough stone, likely quartz or colored glass surrogate rather than true gem diamond
Natural rough stone, likely quartz or colored glass surrogate rather than true gem diamond · Rough crystal / Raw unpolished fragment
Not applicable (Rough, unfaceted raw mineral) Cut
Carat
Estimated 10.0 to 15.0 carats based on visual scale
Color
Fancy Vivid Red / Orange-Red
Clarity
Included / SI2 equivalent due to internal fractures and cloudiness
Shape
Rough crystal / Raw unpolished fragment
Overall Assessment
While visually striking under intense backlighting, this specimen displays physical characteristics inconsistent with genuine diamond rough, pointing instead toward a colored quartz or slag glass material.
Cut Quality
Not applicable (Rough, unfaceted raw mineral)
Brilliance
Low to moderate due to raw surface and internal fracturing
Fire
Minimal white light dispersion visible through the rough red body
Scintillation
Limited flash effect due to lack of standard facet alignment
Proportions
Irregular raw crystal geometry; standard table and depth percentages do not apply
Symmetry
Asymmetrical raw formation
Polish
Raw, unpolished surface with natural growth lines and fracture planes
Fluorescence
Strong red reaction under backlight excitation
Inclusions
Heavy internal feather fractures, needles, and internal stress cracks
Blemishes
Natural surface pitting, rough patches, and cleavage planes
Origin
Natural mineral aggregate or industrial glass slag surrogate
Treatment Detection
Potential surface dyeing or intense backlighting enhancement
Estimated Value
Nominal decorative or mineral specimen value ($20 - $100)
Certification Estimate
Gemological testing laboratory (e.g., GIA, Gubelin) would likely identify as treated or synthetic colored quartz/glass
Investment Potential
Very low; decorative mineral specimen rather than a standard investment-grade gemstone
Similar Diamonds
Red-coated quartz, synthetic corundum, or colored glass rough fragments
Setting Suggestions
Wire-wrapped pendant setting in sterling silver or yellow gold to preserve raw aesthetic
Care & Maintenance
Avoid harsh ultrasonic cleaning, harsh chemicals, and extreme thermal shock due to internal fractures
Interesting Facts
Stunning red backlighting can make ordinary mineral quartz or slag mimic extremely rare fancy red diamonds
