Vintage Jadeite & Diamond Statement Ring in Solid 18K Yellow Gold — Made in Hong Kong SAR, 1992 · One of a Kind

Made in Hong Kong SAR in 1992 and carrying a confirmed 750 hallmark, this ring is not simply a piece of jewellery — it is a document of a particular moment in fine craftsmanship. At its centre sits a natural translucent green jadeite cabochon of 6 × 14mm, bezel-set flush within a broad rectangular frame of solid 18K yellow gold. Two horizontal diamond rails flank the stone above and below — eight natural brilliant-cut diamonds per rail — their sparkle punctuating the architectural calm of the gold with precision and restraint. The ring weighs 9.20 grams — a weight that announces itself the moment it settles on the finger. Discover why 18K gold has long been the standard for significant fine jewellery.

One of a Kind
This is a single, irreplaceable vintage piece. It cannot be reordered, replicated or sourced again. Once it finds its wearer, it is gone — which is precisely the nature of a ring made over thirty years ago by craftspeople who are no longer at that bench.

Design
The ring's architecture is deliberately formal. A wide rectangular face — 13.0mm front height — tapers to a 5.5mm rounded shank, giving it the commanding presence of a signet ring reimagined for a stone rather than an engraving. The jadeite sits at the centre with absolute authority, while the two flat grain-set diamond rails create a horizontal symmetry that is classical in proportion. There is no unnecessary ornamentation. Every element earns its place.

The Jadeite
The oval cabochon measures 6 × 14mm — a natural translucent green jadeite with vivid tone and the characteristic translucency of Grade A verified stone. In East Asian culture, jade has been worn for millennia as a symbol of wisdom, protection, harmony and good fortune. This is natural jadeite; the specific gravity has been verified to authenticate jadeite against nephrite and glass.

Diamonds & Gold
Sixteen natural round brilliant diamonds of 1.2mm each are flat grain-set across two horizontal rails — eight stones per rail — with a verified combined weight of 0.28 carat. All diamonds are natural. The ring body is solid 18K yellow gold throughout, weighing 9.20 grams (approximately 8.49 grams gold mass). The 750 hallmark is stamped on the interior of the shank. Understand what the 750 hallmark guarantees.

Care & Wear · Natural jadeite requires gentle care. Avoid ultrasonic cleaners, steam cleaning and prolonged exposure to chemicals, perfumes or direct sunlight. Clean with a soft damp cloth only. The 18K yellow gold band requires no replating and is naturally resistant to tarnish. Read our complete fine jewellery care guide.

What makes this a collector's piece rather than simply a vintage ring?

Three things converge: its Hong Kong SAR origin and 1992 date, placing it within a specific era of East Asian fine jewellery craftsmanship; its exceptional gold weight of 9.20 grams in solid 18K reflecting commissioning intentions well beyond everyday jewellery; and the combination of Grade A verified natural jadeite with natural diamonds in a formally architectural setting that has no equivalent in contemporary mass-market production. It is the kind of ring that cannot simply be remade. Explore our full fine gold collection.

What does jade symbolise and why is it significant in fine jewellery?

Jade has been revered across East Asian cultures for thousands of years — in Chinese tradition it embodies virtue, wisdom, courage and immortality. Unlike diamonds, which derive significance largely from scarcity and brilliance, jade carries symbolic weight rooted in philosophy and cultural heritage. The vivid green of this stone represents vitality and harmony — qualities that have made jade one of the most meaningful gemstones in the world's oldest jewellery traditions.

Is this Grade A jadeite and what does that mean?

Yes — Grade A jadeite is natural, untreated stone with no polymer impregnation or artificial enhancement. The specific gravity of this stone has been verified to authenticate it as genuine jadeite (not nephrite or glass). No gemological certificate is available for this vintage piece; buyers requiring formal treatment documentation should seek independent assessment prior to purchase, as is standard practice for any significant jade acquisition.

Why does the gold weight of 9.20 grams matter?

Most contemporary fine jewellery rings weigh between 2 and 5 grams. At 9.20 grams of solid 18K gold — approximately 8.49 grams pure gold mass — this ring is almost twice the weight of a substantial modern piece. That weight reflects both the broad architectural design (13.0mm front height, 5.5mm tapered shank) and the craftsmanship standards of its era. You feel this ring when you wear it.

Is this ring suitable for everyday wear and what size is it?

The gold is robust and the grain-set diamond rails are secure. However, jadeite — rated 6.5–7 on the Mohs scale — is more susceptible to impact and chemical exposure than diamond or sapphire. Remove before manual labour, gym use, swimming or applying cosmetics. Set at UK R–S / US 8.5–9.25 / EU 59–60.5 — a larger size that suits most men's ring fingers or works as a statement ring for women. Visit our jewellery care guide for full aftercare advice.
