This designer ring is made of natural Baltic Amber and 925 sterling silver. The ring is hand made by a designer in Poland. This ring size is adjustable and the size of the stone is 0.9" x 0.7". This piece of Amber contains a genuine insect, just like in the movie Jurassic Park! 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.
