This necklace (for a human!) is in the guise of a choke chain. Stainless steel, a spiral weave called Jens Pind Linkage, about 30" long, and weighing 3.67oz (104g).
As with everything I create, this is fully customizable, including color, materials, (steel, bright or anodized aluminum, brass, copper, precious metals, etc.), and more. When you order, add notes about what you’re looking for and I will confirm details with you before getting started.
