Reposhing this item I purchased from @evelinghobrial. Loved it, but ready to rotate for something new. Questions? Leave a comment below! this does not come with the key. the hanging key got lost. I believe this necklace is about 10 Years old just judging by the style. it's is authentic and needs a bit of cleaning. there is scratches and marks from wear and tear. the price reflects this. the Chain is 925. silver the heart is authentic tiffany 925 silver.
