Vintage 18K Yellow Gold Custom-Made Domed Curved Link Collar Necklace 48.6 Grams

One of a Kind, custom handmade (1986 Main Line, PA) Structured, Curved Choker / Collar Link Necklace in Solid 18K Yellow Gold. There is not another necklace like it. Absolutely stunning. 46.8 Grams (confirmed weight and Karat by established jeweler)  SINGLE OWNER (myself.) Has been kept in a jewelry box.  Lays beautifully. The detail is hard to describe so please refer to photos/video. Notice the slightly textured links. All handcrafted.  The underside of the necklace as seen in a few photos is curved / indented so it is not only really comfortable to wear but lays properly - similar to a dome style.    Hallmark says 750 for 18k, my camera can not pick up the detail.  Measures: approx 6.35-7mm wide - it's hard to be exact, however 6.5mm would be accurate. Laying flat the length is approx 11.5 - this is measured from the top of the closed clasp to the bottom front of the necklace.  Overall length - between 16.5 and 17.5 -(I can be more precise if need be, pls message.) *I put 17 in desc.  Weight: 46.8 grams on jeweler's scale. (47 grams based on my kitchen scale)  Color/Condition: Yellow gold - however the smaller pieces between the bar links are a bit lighter so there is dimension.. Condition: Great - there are normal signs of wear if you look very closely in line with age but it's in beautiful condition. It has not been worn for a very long time. The clasp has no issues. It has been kept in a box.
