Loop is double-strung with strong nylon coated wire and hanging from an silk cord with lobster-claw clasp.
Please let me know what length you'd like the cord - I have it on a 22 inch cord to hang down below the neckline as shown at the top, though I can make it shorter if you'd prefer it more like the second example where it hangs above the neckline.
This item is available online in my etsy shop!
