David Yurman longe necklace adjustable

Purchased new from another auction site 6 different necklaces but never wore. Please note that this is a new item but is still secondhand as I am not the original owner. I have not had this piece authenticated by David Yurman, as they do not offer the service of authenticating items. I have compared it with the same models being sold on Poshmark and they look identical in terms of markings. This is being sold at a steep discount because I have not had the item professionally authenticated by a jeweler as this can be costly and is time consuming. Please be aware of this before purchasing. Reasonable offer welcome Hallmarked: © D.Y. 925
