Burmese Amber: History and Geological Record
Burmese amber, often called burmite, is fossilized resin recovered in Myanmar. Hukawng Valley in Kachin State is its best-known source, but Myanmar has several amber-bearing regions and ages vary by locality. Zircon dating of material from the Hukawng amber-bearing deposits constrains them to about 98.79 ± 0.62 million years ago (Ma), in the Late Cretaceous. This is a deposit-age estimate, not the exact age of every piece.
Historical use and trade
A 2003 field study cites historical sources reporting that amber from the Hukawng Valley was known by at least the first century CE and traded from northern Myanmar into Yunnan. This describes a long trade history; it does not establish a single modern discovery date or the provenance of every piece offered today.
How the geological age was revised
Earlier estimates for the amber-bearing rocks varied. In 2012, researchers dated zircon crystals from volcanic material associated with the Hukawng amber-bearing deposits to 98.79 ± 0.62 Ma. They interpreted this as a maximum age constraint for the amber-bearing deposit, placing it in the earliest Cenomanian of the Late Cretaceous. The date belongs to the geological deposit and associated material, not to each individual specimen.
Myanmar amber has more than one age
Hkamti amber is associated with tuffs dated to a weighted mean of 109.7 ± 0.4 Ma. Amber-bearing layers at Tilin in central Myanmar are estimated at about 72.1 Ma. These are distinct localities and geological records; they should not be combined into one age for all Burmese amber.
Why the inclusions matter
Researchers study organisms and plant material preserved in amber to learn about ancient ecosystems. Conclusions depend on the specimen and its documented context. A traded inclusion without collection records may have uncertain locality or provenance.

Summary
Research places Myanmar’s amber-bearing deposits at different points in the Cretaceous. Zircon dating constrains Hukawng amber-bearing deposits to about 98.79 ± 0.62 Ma; Hkamti and Tilin amber have separate, older and younger age estimates. These are geological estimates for deposits and associated strata, not exact dates for every specimen.
Historical publications describe amber trade in northern Myanmar long before modern geology. Later field studies and fossil research have refined what can be said about its origin and inclusions. Avoid calling all Burmese amber the oldest, rarest, or most valuable: such comparisons need a defined sample, market, and supporting evidence.
