Natural rough mineral, likely quartz or heavily included industrial diamond/bort
Natural rough mineral, likely quartz or heavily included industrial diamond/bort · Rough, unpolished, irregular pebble or fragment
Not applicable (uncut rough crystal) Cut
Carat
Estimated 2.0 - 3.5 carats based on visual scale
Color
Low commercial grade, milky white to translucent with brownish surface staining
Clarity
I3 (heavy inclusions, fractures, and surface irregularities)
Shape
Rough, unpolished, irregular pebble or fragment
Overall Assessment
This appears to be a heavily weathered, low-grade natural mineral specimen (likely quartz or industrial bort diamond). It lacks gem-quality clarity, color, and cut characteristics, making it suitable only as a raw mineral specimen rather than a faceted gemstone.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Poor due to lack of facets and high opacity
Fire
Negligible due to lack of standard gemstone cutting and inclusions
Scintillation
Absent due to opaque and unfaceted surface structure
Proportions
Not applicable to rough stones
Symmetry
Asymmetrical due to natural formation and wear
Polish
Raw, unpolished matrix texture
Fluorescence
Cannot be reliably determined without UV testing
Inclusions
Heavy internal fracturing, cloudiness, mineral spots, and iron oxide staining
Blemishes
Rough surface pitting, natural cleavage lines, and adhere matrix debris
Origin
Alluvial secondary deposit or rough matrix extract
Treatment Detection
No evidence of artificial enhancement; completely natural as found
Estimated Value
Minimal (specimen value only, under $10 USD as a mineral sample)
Certification Estimate
Unlikely to be certified by major labs (GIA/AGS) as it is rough industrial-grade material
Investment Potential
None as a gem investment; purely educational or mineral collection value
Similar Diamonds
Industrial grade diamond bort, low-grade industrial rough fragments, or milky quartz pebbles
Setting Suggestions
Wire-wrapped raw mineral pendant or kept as a raw mineral collection specimen
Care & Maintenance
Wash gently with mild soap and water to remove surface dirt; store separately to prevent scratching other materials
Interesting Facts
Rough stones like this represent the vast majority of mined diamonds, most of which end up in industrial applications rather than jewelry
