A few useful guidelines are these:
- There is no true amber from S.America. 'Amber' from Colombia is copal - resin usually not more than 30,000 years' old that has not yet acquired the hardness and stability of amber.
- Similarly, there is no true amber known to come from anywhere in Africa. African 'amber' specimens in the great museums of the world were discredited and reclassified as very young copal by accurate radio carbon dating work done in the 1980's.
- S.E. Asia and Australasia (esp. Malaysia and Indonesia) produce mainly copal (local names dammar or gum) but there is production of some amber too.
- Mexican and Caribbean amber is chemically distinctive from amber formed in the states bordering the Baltic Sea and southerly through Germany, Poland and Ukraine. Both amber and copal are found in the Dominican Republic.
- 80% of the world's production of amber comes from the Baltic region.
- The amber trade has a murky past. There was a history in the 20th century of the importation of both copal and amber from the Americas to blend with amber recovered in the Baltic states (incl Russia, Poland and E.Germany. This has essentially ceased since 1989.
