Succinite, and why the name matters
Baltic amber — succinite — comes from the Baltic region and is distinguished by its succinic acid content, which is why it is identifiable in a laboratory rather than merely assertable in a catalogue. It is the material with the longest documented trade history and the one the Gulf market recognises by name.
Other ambers are not lesser materials. Dominican amber is prized for blue fluorescence, Burmese amber for hardness and age. But they are different materials and should be sold under their own names, which is a discipline the trade does not always observe.
