    Hi

    "The fossilized resin is found throughout the world, although much of the amber used for jewelry derives from deposits in Europe's Baltic region and from the Dominican Republic. Most ambers are 20 million to 130 million years old. However, recognizable ambers have been discovered that originated around 240 million years ago.

    Because amber is an organic material, its age can be determined by carbon-14 radioisotope dating, but only if the sample is less than about 40,000 years old. The age of much older ambers can be inferred from the age of the surrounding sediments. Radioisotopes with half-lives much longer than that of 14C are used to date the sediments."
