Knocker 9ct Recycled Yellow-Gold And Sterling-Silver Ring

Otiumberg doesn’t need to chase trends – its contemporary designs are ones you’ll wear forever, trust us. The brand's much-loved Knocker ring is cast with solid sterling silver and embellished with a circular door-knocker pendant in solid 9-carat yellow gold (which – like all of the brand's solid gold – is recycled, FYI). This mixed-metal beauty works like a dream as a stand-alone piece, but we’re stacking ours up with other styles from the London-based label.
