Non-fossil (Jewelry/Synthetic Crystal)
Inapplicable (Jewelry) • Synthetic gem; specifically a faceted crystalline structure, not a biological fossil.
Geological Period
Modern (Anthropocene)
Estimated Age
0 million years (Modern manufacture)
Preservation Type
None (Industrial manufacture via Czochralski process or CVD)
Condition Assessment
Excellent (relative to jewelry standards); shows clean facets and secure setting.
Taxonomic Classification
Non-biological; Mineralogical classification: likely Cubic Zirconia or synthetic Diamond (Carbon/Zirconium Dioxide)
Morphological Description
Brilliant-cut faceted gemstone set in a four-prong metallic band. Exhibits optical properties such as high dispersion (fire) and high refractive index.
Rock Matrix
None (Metal alloy band, possibly sterling silver or gold plating)
Formation & Location
Likely an industrial laboratory or manufacturing facility; common worldwide in retail markets.
Size & Dimensions
Central stone approximately 6-8mm in diameter (approx. 1.0 - 2.0 carat equivalent).
Value & Rarity
Estimated Market Value
$20 - $200 (depending on metal content and stone material)
Auction Estimate
$10 - $50 (General auction range for costume or standard retail jewelry)
Rarity Assessment
Common (Mass-produced item)
Scientific Significance
Negligible for paleontology. Significant for materials science or gemology regarding synthetic crystal growth and optics.
Preparation Recommendations
Ultrasonic cleaning or lukewarm soapy water with a soft brush; store in a padded jewelry box to prevent scratching.
Notable Features
Specimen is a piece of jewelry misidentified as a fossil. It lacks organic structure, petrification, or sedimentary matrix.
