Amber with Insect Inclusion
Insecta indet. (possibly Diptera or Coleoptera) • Body fossil (amber inclusion, invertebrate)
Geological Period
Paleogene (Oligocene or Eocene)
Estimated Age
30 to 45 million years
Preservation Type
Three-dimensional organic preservation trapped in fossilized tree resin (amber), exhibiting exceptional soft-tissue and structural detail preservation.
Condition Assessment
Very Good. The amber piece is well-polished and stable, though the inclusion is slightly obscured by internal refraction and surface angles.
Taxonomic Classification
Phylum Arthropoda, Class Insecta
Morphological Description
Elongated, dark, centrally positioned body silhouette entombed within transparent, polished amber. Surface shows typical resin flow lines and a warm, honey-orange to reddish-brown coloration with smooth, cabochon-like curvature.
Rock Matrix
Fossilized tree resin (amber), lacking a traditional mineral rock matrix, highly polished for display.
Formation & Location
Baltic region (Baltic Amber) or Dominican Republic
Size & Dimensions
Approximately 2 to 3 cm in length, consistent with medium-sized amber cabochons containing single insect inclusions.
Value & Rarity
Estimated Market Value
$50 - $150
Auction Estimate
$75 - $200
Rarity Assessment
Common to Uncommon, depending on the exact taxonomic identification of the enclosed insect.
Scientific Significance
Provides direct evidence of ancient forest ecosystems, paleoclimate, and insect morphology from the Cenozoic era, offering pristine preservation unachievable in standard sedimentary rocks.
Preparation Recommendations
Store away from direct sunlight, UV light, and extreme heat to prevent oxidation and crazing. Keep in a stable humidity environment and handle with soft cloths or gloves.
Notable Features
Clear, warm honey coloration with a distinct, darkened organic inclusion suspended cleanly in the optical center of the polished gem.
