Pre-Loved 9ct Yellow Gold Black Onyx Cushion Signet Ring Hallmarked Size W

Black and gold is one of the most enduring combinations in jewellery, and this pre-loved 9ct yellow gold onyx signet ring is a masterclass in why. A cushion-shaped black onyx tablet sits set into a wide, tapered yellow gold shank, framed by a serrated millgrain border that gives the setting a beautifully detailed, considered finish. It is a ring that wears with authority — substantial, confident and completely timeless.

The black onyx — deep, glossy and richly coloured — has been used in fine jewellery for centuries, prized for its depth of colour and its striking contrast against yellow gold. Here it sits in a classic bezel-style setting that holds the stone securely and frames it perfectly, the millgrain border adding a vintage decorative touch that elevates what might otherwise be a simple design into something genuinely special. Yes, this is real gold, fully hallmarked and confirmed as genuine 9ct yellow gold with a 375 purity mark.

At 4.40g, this ring has real weight and presence on the finger — the wide tapered shank giving it the kind of heft that feels luxurious, particularly in a larger size. It arrives in good condition with wear consistent with its vintage character, the onyx intact and the gold retaining its warm colour throughout. A signet ring of this scale and quality is a piece you wear every day and reach for without thinking — the kind that becomes part of you.

Pre-loved and ready for a new chapter, this 9ct gold black onyx signet ring is a wonderful find for anyone who appreciates classic, bold jewellery with genuine substance. Beautifully gift wrapped and ready to wear.
