Amber Encyclopedia Entry #5: Burmese Amber with Enhydro Inclusion

This museum-grade Burmese amber ring features a rare enhydro inclusion — a visible water bubble suspended inside golden fossilized resin. The amber dates back to the mid-Cretaceous period (~99 million years ago) and comes from the Hukawng Valley of northern Myanmar, one of the world’s richest amber fossil deposits.

Though wearable as jewelry, this piece is first and foremost a scientific specimen — a natural capsule of prehistoric fluid preserved since the age of the dinosaurs.
