Baltic Amber Cabochon with Insect Inclusions
Indeterminate insect inclusions cf. Diptera / Hymenoptera • Amber inclusion, body fossil (arthropod and plant inclusions)
Geological Period
Paleogene (Eocene epoch)
Estimated Age
33 to 56 million years old
Preservation Type
Three-dimensional exceptionally detailed preservation trapped in fossilized tree resin (amber), preserving delicate soft-tissue structures of small arthropods
Condition Assessment
Very Good. The cabochon is professionally polished with high clarity in the lower half, though the upper half is darker and partially obscured, with minor internal stress fractures typical of natural amber.
Taxonomic Classification
Phylum Arthropoda, Class Insecta, Order various (Diptera, Hymenoptera), Family various
Morphological Description
The specimen features a polished oval cabochon shape displaying distinct internal inclusions, including small dark fragmented insect body parts, wispy organic debris, and golden-brown particulate matter suspended within the resin matrix. The amber exhibits a dual-tone coloration, transitioning from a darker, deep brownish-black upper zone to a translucent, bright golden-orange lower zone.
Rock Matrix
Fossilized tree resin (succinite/Baltic amber) without traditional rock matrix, highly polished into a smooth gem-grade cabochon
Formation & Location
Samland Formation, Kaliningrad region, Russia (Baltic amber region)
Size & Dimensions
Approximate dimensions are 25mm to 35mm in height, typical for polished amber jewelry cabochons containing small insect inclusions
Value & Rarity
Estimated Market Value
50 to 150 USD
Auction Estimate
40 to 120 USD
Rarity Assessment
Common, as Baltic amber with small insect inclusions is widely available on the market, though individual inclusion configurations remain unique.
Scientific Significance
Amber inclusions provide exceptionally preserved evidence of ancient forest ecosystems, paleoclimate conditions, and insect evolution during the Eocene epoch, capturing microscopic anatomical details rarely found in standard sediment fossils.
Preparation Recommendations
Store away from direct sunlight, extreme heat, and volatile organic solvents (such as acetone or alcohol) to prevent crazing, oxidation, and degradation of the amber. Keep in a stable humidity environment and display in a UV-protected case.
Notable Features
Distinct bi-color zonation within the amber matrix, dividing the stone into a dark upper cap and a transparent, warm golden lower window highlighting trapped particulate debris and fossilized inclusions.
