Sterling silver and natural mined black diamonds

This is a pre-owned pendant necklace. The pendant is circular and made of sterling silver, marked '925'. It features an open design with interconnected circles, some of which are encrusted with black diamonds. The chain is a beaded style, also made of sterling silver. The pendant has a diameter of approximately 1 inch. The necklace weighs 7 grams. I will ship in a box. Please note the video is the same style necklace but different chain.
