Unidentified fossil resin with potential microscopic inclusions • Amber inclusion / organic resin fossil
Geological Period
Paleogene (Eocene epoch)
Estimated Age
33 to 50 million years old
Preservation Type
Fossilized tree resin (amber) preserving organic matter in three dimensions with exceptional cellular detail where inclusions are present
Condition Assessment
Good to Very Good condition; well-polished, stabilized, intact, with minor surface crazing typical of aged amber specimens
Taxonomic Classification
Phylum: Arthropoda (inclusions likely), Class: Insecta / Arachnida, Order: Various, Family: Various
Morphological Description
Polished, rounded amber nodules displaying translucent to transparent golden-brown and honey-yellow coloration, exhibiting internal flow lines and dark organic particulate matter suspended within the fossilized tree resin.
Rock Matrix
Suspended in a modern floating membrane display case (suspension frame), originally derived from glauconitic sand layers (Blue Earth formation)
Formation & Location
Samland Peninsula, Kaliningrad Oblast, Russia / Baltic Sea region
Size & Dimensions
Each piece measures approximately 1.5 cm to 2.5 cm in length, fitting standard small collector display frames
Value & Rarity
Estimated Market Value
$30 - $80 USD
Auction Estimate
$20 - $50 USD
Rarity Assessment
Common, widely available from the Baltic region, though specific rare inclusions can increase value significantly
Scientific Significance
Provides crucial insights into Eocene forest ecosystems, paleoclimatology, and ancient insect evolution through exceptional three-dimensional preservation of soft tissues
Preparation Recommendations
Store away from direct sunlight, extreme heat, and low humidity to prevent oxidation and crazing; clean gently with a soft, dry cloth; avoid chemical solvents like alcohol or acetone
Notable Features
Vibrant honey-yellow luminescence when backlit, showcasing rich internal color variation, fluid resin flow patterns, and deep amber warmth
