This very nice heart pendant is made of natural, faceted, cognac color, Baltic Amber and 925 Sterling Silver. The color of Amber depends on the age of the Amber and where the Amber piece was discovered. The size of this pendant is 0.85" x 0.8". Our Baltic Amber is 100% natural from Lithuanian, guaranteed, and our silver is stamped 925 sterling. (Please note, the chain is not included with the pendant, and since Amber is natural all pieces might vary slightly from the picture.)7
