Two Hearts, One Enduring Symbol of Love
Double-Heart Natural Diamond Ring in Solid 18K White Gold
Crafted from solid 18K (750) white gold and finished with a brilliant rhodium polish, this ring celebrates romance through a beautifully balanced double-heart design. Each open heart cradles a natural round brilliant diamond at its centre, while dozens of smaller natural diamonds delicately trace the heart silhouettes and continue along the shoulders of the band — creating continuous sparkle from every angle.
The graceful open-heart architecture gives the design a light, refined appearance while allowing the diamonds to become the true focal point. Precision pavé setting and minimal visible metal maximise brilliance, creating an elegant piece that feels timeless rather than fashionable. Whether chosen as a promise ring, anniversary gift, or simply a meaningful addition to a fine jewellery collection, the design represents two hearts connected in harmony.
Estimated to contain approximately 0.70–0.75 carats of natural diamonds in total, the ring weighs 3.19 grams — offering the reassuring substance of genuine fine jewellery while remaining delicate enough for daily wear. Beautifully balanced, romantic and enduring, it is a piece designed to be treasured for generations. Discover why 18K gold remains the benchmark for fine jewellery and what sets it apart from other gold standards.

What makes this a fine jewellery piece rather than fashion jewellery?
This ring is crafted from solid 18K white gold — not gold-plated, not gold-filled, but genuine 750-hallmarked gold throughout. Combined with natural round brilliant diamonds set in precision pavé, it meets the definition of fine jewellery in every sense. It will not tarnish, corrode or fade with time. Explore our full 14K and 18K fine gold collection to see the breadth of our fine jewellery range.
What does the double-heart design symbolise?
The two open hearts — each cradling its own diamond — represent two souls in harmony. The design is particularly meaningful for couples, best friends, or a mother and child. The diamonds at the centre of each heart speak to the clarity and brilliance at the core of every meaningful relationship. As an anniversary gift, promise ring or romantic gesture, this design carries intention that goes beyond the aesthetic.
Are the diamonds natural or lab-grown?
All diamonds in this ring are natural. The two centre stones are natural round brilliant diamonds of approximately 3mm each, and all 46 accent diamonds across the heart silhouettes and band shoulders are natural. The estimated total diamond weight of 0.70–0.75 carats reflects the full natural diamond content of the piece.
Why choose 18K gold over 14K or 9K for this ring?
18K gold contains 75% pure gold, giving it a richer tone and a prestige that 14K or 9K cannot match. For a diamond ring designed to celebrate love and be worn for decades, 18K is the natural choice — it holds its colour beautifully, is hypoallergenic for most wearers, and pairs flawlessly with the rhodium finish that keeps white gold crisp and bright. Read our guide on 14K vs 18K gold to understand the full difference.
What ring size is this, and can it be resized?
This ring is set at UK M / US 6.5 / EU 52, with an inner diameter of 16.6mm and a circumference of 52mm — a popular mid-range size that fits many wearers. As with all pavé-set diamond rings, resizing should only be carried out by an experienced fine jeweller to avoid disturbing the stone settings. We recommend professional assessment before resizing.
How should I care for this ring to keep it looking its best?
Rhodium-plated 18K white gold is highly durable but benefits from simple care: remove the ring before swimming, bathing or handling chemicals, and clean gently with a soft damp cloth. The rhodium finish may gradually wear over many years — a jeweller can re-plate it to restore its original brilliance.

Caring for Your Fine Gold Piece
14k and 18k gold is a precious metal investment. With proper care it holds its colour and quality indefinitely — fine gold does not tarnish, but it can scratch and dull without attention.
| Daily wear | Remove during heavy physical activity, cleaning, and gardening |
| Cleaning | Warm water, a drop of mild dish soap, soft brush — rinse and dry with a lint-free cloth |
| Storage | Store separately — gold scratches easily when touching other metals |
| Professional care | Annual professional polish recommended for fine pieces |
| Avoid | Chlorine, bleach, harsh chemicals, and ultrasonic cleaners for pieces with stones |
