This is a delicate and classic 3-stone, graduated, bright white diamond necklace in 10K white gold. The pendant drops down 7/8" (2.2 cm) and the chain measures 18" in length. Both pendant and chain are stamped 10K. I don't know the total carat weight, but the necklace as a whole weighs 1.602 grams. Dress it up or dress it down!
