Hidden Halo Diamond Engagement Rings — Hatton Garden, London

The hidden halo is one of the most sought-after styles in contemporary fine jewellery. A secret circle of pavé-set diamonds nestled just beneath the centre stone — invisible from above, yet from the side it creates a breathtaking halo of light that elevates the entire ring. Clean and elegant at first glance. Dazzling on closer inspection.

Every ring in this collection is handcrafted in our Hatton Garden, London workshop, set with ethically sourced diamonds and finished in UK Hallmarked precious metals.

Available Centre Stone Shapes

  • Round Brilliant — unrivalled fire and brilliance; the most popular choice for hidden halo settings
  • Oval — elongates the finger and creates a larger visual footprint
  • Radiant Cut — bold, modern, with exceptional sparkle
  • Emerald Cut — understated sophistication with a hall-of-mirrors effect
  • Princess Cut — geometric precision amplified by the hidden halo
  • Marquise — distinctive, elongated shape that maximises carat weight

Lab-Grown or Natural Diamonds

Both are real diamonds — chemically, physically and optically identical. Lab-grown diamonds offer 30–50% more value for the same quality. Natural diamonds carry the romance of geological rarity. Both options are available across this collection. Certification details are listed on individual product pages where applicable.
