Natural quartz crystal with inclusion, commonly misidentified as diamond in rough forms, but this specimen appears to be a quartz variety (such as citrine or quartz with rutile/tourmaline inclusions)
Natural quartz crystal with inclusion, commonly misidentified as diamond in rough forms, but this specimen appears to be a quartz variety (such as citrine or quartz with rutile/tourmaline inclusions) · Rough crystal / Partial tabular cut with natural crystal habit visible
Poor / Unfinished raw crystal form Cut
Carat
Estimated around 15-25 carats equivalent volume
Color
Light yellow to greenish-yellow with brownish patches
Clarity
I3 (Heavy inclusions, internal fractures, and foreign crystal needles visible)
Shape
Rough crystal / Partial tabular cut with natural crystal habit visible
Overall Assessment
An intriguing raw mineral specimen featuring a large crystal enclosed within another matrix, offering high aesthetic value for mineral collectors despite low commercial gemstone value
Cut Quality
Poor / Unfinished raw crystal form
Brilliance
Low due to heavy internal inclusions and lack of standard faceting
Fire
Minimal dispersion
Scintillation
Poor, restricted by opacity and internal fracturing
Proportions
Non-standard raw mineral proportions
Symmetry
Asymmetrical due to natural growth and partial cutting
Polish
Semi-polished face with visible surface texture and abrasions
Fluorescence
Inert to faint
Inclusions
Prominent needle-like inclusions (likely tourmaline or rutile), internal feathers, and fractures
Blemishes
Surface scratches, pitting, and natural crystal etching
Origin
Pegmatite or hydrothermal vein mineral deposit
Treatment Detection
No obvious treatments detected; appears completely natural
Estimated Value
Low commercial value ($20 - $100 as a mineral specimen)
Certification Estimate
Not applicable for major gemological diamond labs (GIA/AGS); local colored stone lab report
Investment Potential
Collector mineral specimen value only, not suitable for gemstone investment
Similar Diamonds
None, as this is a colored quartz crystal rather than a diamond
Setting Suggestions
Wire-wrapped pendant or bespoke organic metal setting to preserve raw aesthetic
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and hard impacts due to internal fractures
Interesting Facts
The large dark needle inclusion trapped inside creates a striking window effect, highly prized by mineral collectors
