This is a gorgeous high end necklace. Natural diamond accents and black sapphires. Very modern and classic. Just over 20" long. 54.6 grams. 4/10" wide. Marked 925. Guaranteed Sterling Silver and diamonds. Exquisite piece. The links on this fine necklace do get a little twisted/stuck when in your jewelry box . Each link fits snugly into the other and may need some wiggling prior to ear. This same snug feature is what keeps the necklace laying flat and classy when wearing. Originally priced at $1000. All of my jewelry comes gift boxed.
