Dominica is not only one of the main producing areas of amber, but also a place where amber contains many types of fossils. Although the mining of Dominican amber has been around for hundreds of years, the amber it produced until the last 50 years is widely known. At present, about 10% of the amber sold in the international market comes from here.
Dominica Overview
The Dominican Republic is an island country with a tropical rainforest climate in the north and east, a savanna climate in the southwest, and a rapid evolution of the island's biological species. Amber contains the world's highest number of plants and insects. The three larger mines of Los Cacao S, Palo Quemado and Loma El Penon produce high quality amber, especially the world famous blue amber.
Dominican amber generation
Dominican amber is produced from a resin called the algarrobo of Hymenaea protera. Interestingly, the carob produces these resins originally to drive away from insects and prevent the growth of fungi. It is not expected that the resin will be a perfect inclusion for the preservation of insects.
