【Origin】 Lithuania, Baltic Sea 【Age】 Eocene Epoch (approximately 45 million years ago) 【Size】 Approximately 12 x 10 x 8 mm Amber is formed when tree resin (sap) is buried underground and solidifies over a long period of time. After being buried for tens of millions of years, the resin transforms into a fossil. This amber solidified with ancient insects trapped inside when it flowed from the tree as sap. Two insects are included. We have other fossils for sale, so please consider them as well. ※ Case not included. #Luna'sFossil Insect-containing Amber
