This collar/choker necklace is made from Sterling silver heavy chain links 8mm by 1.7mm with a removable O Ring.
The O ring is approx 25 mm ( 1 inch in diameter) and 2mm in thickness. Strong but not recommended for anything but decorative use.
A 15mm Lobster clasp closes the collar on the back.
The collar links are individual soldered shut with silver; they are then tumbled to harden the silver and polished to a high sheen.
Made to order to your requested size.
The necklace can be worn loose as a necklace or you can wear as a collar choker.
I ship by recorded delivery and ship gift wrapped.
