The specimen shown in the image is not a diamond; it appears to be a rough quartz pebble, likely heavily stained with iron oxide (hematite/limonite).
The specimen shown in the image is not a diamond; it appears to be a rough quartz pebble, likely heavily stained with iron oxide (hematite/limonite). · Irregular / Rough Pebble
Not Applicable (Rough, un-cut stone) Cut
Carat
Not applicable for a non-gem rough mineral specimen of this type, but visually estimated at roughly 10-15 carats equivalent weight.
Color
Yellowish-brown with reddish-brown staining (Fancy brownish-yellow in gemological terms if polished).
Clarity
Included / Opaque due to heavy internal fractures and mineral staining (I3 equivalent).
Shape
Irregular / Rough Pebble
Overall Assessment
The specimen is a naturally weathered quartz pebble with iron staining rather than a diamond or high-value gemstone. It holds value primarily as a geological curiosity.
Cut Quality
Not Applicable (Rough, un-cut stone)
Brilliance
Poor to None in its current rough and opaque state.
Fire
None visible due to lack of faceting and opaque nature.
Scintillation
None
Proportions
Non-standard, natural raw pebble shape.
Symmetry
Asymmetrical (Natural rough formation)
Polish
Unpolished (Natural weathered surface)
Fluorescence
Cannot be determined without UV testing, though typical quartz may show weak inertness or patchy fluorescence.
Inclusions
Numerous internal fractures, micro-fissures, and iron-staining pockets visible throughout.
Blemishes
Surface pitting, abrasion marks, and iron oxide crusts from weathering.
Origin
Alluvial deposit, riverbed, or weathered soil deposit containing quartz.
Treatment Detection
No artificial treatments detected; natural weathering and mineral staining.
Estimated Value
Nominal value as a mineral specimen or rock hound find (less than $5).
Certification Estimate
Major grading labs like GIA or AGS do not grade rough common quartz pebbles; requires basic gemological identification only.
Investment Potential
None; purely a decorative or educational mineral sample.
Similar Diamonds
None, as this is quartz, not diamond.
Setting Suggestions
Wire-wrapping in sterling silver or copper if used for rustic jewelry.
Care & Maintenance
Standard cleaning with mild soapy water and a soft brush; avoid harsh acids if iron staining is desired for appearance.
Interesting Facts
Quartz is one of the most abundant minerals on Earth, often mistaken for precious rough stones by amateur prospectors due to interesting coloration from mineral stains.
