This ring is made of natural, butterscotch Baltic Amber and 925 sterling silver. The ring is hand made by a designer in Poland. This ring size is adjustable and fits most fingers. The size of the Amber stone is 1.1" x 1" and the ring weighs 10 grams. The color of Amber depends on the age of the Amber and where the Amber piece was discovered. Our Baltic Amber is 100% natural from Lithuania, guaranteed. Please note since Amber is natural all pieces might vary slightly from the image and may contain natural imperfections.
