Rovno amber, occasionally called Ukrainian amber,[1] is amber found in the Rivne Oblast and surrounding regions of Ukraine and Belarus. The amber is dated between Late Eocene and Early Oligocene, and suggested to be contemporaneous to Baltic amber (Prussian Formation). Major exploration and mining of the amber did not start until the 1990s.
