A hallmarked solid 100% recycled sterling silver pendant inspired by countersink drill bits. The removable pendant is plated in black rhodium giving it an edgy gun metal grey finish. The chain is a .95 gauge, 30"/75cm long box chain in sterling silver (long enough to fit over the head) with a hand-stamped "Edge." tag. From the Mechanical Collection. Matching earrings are available. *Black Rhodium is from the Platinum family of precious metals. It gives a transparent "black" veil to the silver resulting in a cool, gun-metal grey colour. Plating will gradually fade with wear.
