Round Diamond Engagement Rings — Hatton Garden, London

The round brilliant cut is the world's most popular diamond shape — and for good reason. With 58 precisely aligned facets engineered to maximise light return, it delivers brilliance, fire, and scintillation that no other cut can match. Every ring in this collection is handcrafted in our Hatton Garden, London workshop by expert jewellers.

Available Styles

• Classic Solitaire — one round diamond, one perfect band. Available in 4-prong and 6-prong settings in platinum, white gold, yellow gold and rose gold.
• Halo & Hidden Halo — a circle of pavé diamonds surrounds the centre stone, amplifying its size and sparkle.
• Pavé & Side-Stone — diamonds set along the band for continuous sparkle from every angle.
• Vintage-Inspired — milgrain edging and floral motifs with modern Hatton Garden precision.
• Three-Stone Trilogy — a round brilliant centre flanked by two side stones, representing past, present and future.

Lab-Grown or Natural Diamonds

Both are real diamonds — chemically, physically and optically identical. Natural diamonds offer geological rarity and heritage. Lab-grown diamonds offer 30–50% more value for the same quality. Both options are available across this collection.
