Baltic Amber is 40 to 60 million years old and well known to collectors as the finest jewelry-quality Amber in the world due to its hardness and age. The Greeks, Romans and people of the time called it "Northern Gold" . Here you will find some of the finest designer-made Baltic Amber, each piece set in Sterling silver.
