The necklace is a large disc 2 3/4 inch across, one side is covered with rings the other side is the YSL mark and what appears to be Saint Laurent’s hammered metal finish, the chain is 34 3/4 inches with out hook and ring I purchased this item in California at a fundraising event (with estate items)
It was purchased at a small fundraising event for the Society for Creative Anachronism ( S.C.A a historical education and re-creation group). It was purchased approximately October of 2001, It was a donation based event so the previous owners are un-known Members attended from all over the western USA and some from overseas I never looked into the item until a few years ago and can only recognize it as a Saint Laurent item, Considering the caliber of attendees the item could be a original item by Saint Laurent himself and I have been able to find nothing like it in the years I’ve been looking
