Baltic Amber with Plant and Insect Inclusions
Indeterminate insect fragments and botanical matter preserved in fossilized resin (cf. Diptera / Pinophyta resin) • Body fossil and amber inclusion, organic invertebrate/plant fossil
Geological Period
Paleogene (Eocene epoch)
Estimated Age
33 to 56 million years
Preservation Type
Amber preservation (fossilized tree resin encasement providing three-dimensional soft-tissue and hard-part preservation)
Condition Assessment
Very Good. The amber is well-polished and stable with clear transparency in specific angles, though internal inclusions are partially obscured by dark organic debris and natural resin cloudiness
Taxonomic Classification
Phylum Arthropoda, Class Insecta / Phylum Tracheophyta
Morphological Description
The specimen exhibits a polished, irregular cabochon shape with deep amber to dark brown tones. Internal features show flow lines, cloudiness, dark carbonized organic debris, fragmented insect appendages, and potential plant trichomes or resin-trapped particulate matter.
Rock Matrix
Amber (fossilized tree resin) with polished exterior surface, lacking traditional sedimentary rock matrix
Formation & Location
Baltic Sea region, specifically the Samland Peninsula in Kaliningrad, Russia, derived from the Blue Earth formation
Size & Dimensions
Approximately 3 cm in maximum length, falling within standard dimensions for cut and polished amber collector cabochons
Value & Rarity
Estimated Market Value
$50 - $150 USD
Auction Estimate
$40 - $100 USD
Rarity Assessment
Common, as Baltic amber with organic debris is frequently recovered, though specimens with exceptionally clear insect specimens command higher rarity ratings
Scientific Significance
Provides crucial data on Eocene forest paleoclimates, amber-producing conifer flora, and the microscopic composition of ancient forest floor resin traps
Preparation Recommendations
Store away from direct UV light and extreme heat to prevent oxidation and crazing. Clean with a soft, dry cloth; avoid chemical solvents like alcohol or acetone which dissolve amber
Notable Features
Rich deep-orange and dark brown coloration gradients with trapped particulate layers, dark structural inclusions, and a high-gloss master polish highlighting internal resin flow patterns
