Vintage 999 silver Three Strand Rope Necklace shop USA with box

Product Name: Vintage 999 silver Three Strand Rope Necklace shop USA with box
This necklace is amazing! It is 3 strands of silver. One side of hangtag is stamped 999 silver and other side of hangtag is stamped USA. I have seen this same necklace on internet with wide variations in prices, so I am just describing it as what is on hangtag and as shown in photos. There is a 4” extender chain. Please see all photos for lengths and details and condition. I am not a jeweler, and though I have tools for measuring widths of stones and chains, rope chains are not easy in terms of accurate measurements for me. It looks like each strand is about 3 mm, being about 10 mm across all 3, but please decide for yourself by looking at photos. Necklace is pre-owned, and may require some untwisting/untangling after its trip through the mail. I have seen a shop similar style by the same designer being made by linking 3 separate bracelets together, but this necklace only has one main clasp. I will include a gift box.
