Large Sterling Silver Cerdanya Cross Pendant and chain Biker Medieval necklace

How can I put this - this vintage unisex chain and pendant are pretty badass. The form is a modified Cerdanya cross in an eight sided quatrefoil framework. The chain is attached to either side of the frame; has a hook (sometimes called a Tiffany) closure. Heavy oval links. Marked 925 and tested sterling silver. Whopping 41.3 grams! Great condition, slight surface marks - this appears to have been very lightly pre-cherished. 18.75” chain which includes the pendant. pendant 1.875” x 1.5”
