This three-stone lab diamond engagement ring brings together a bold centre stone and elegant pear-cut side stones in bright 18K white gold. With a 2.01ct E VS2 lab-grown diamond at the centre and a total diamond weight of approximately 2.74 carats, it delivers serious sparkle with a timeless, balanced silhouette.

Design & Details

The focal point of this ring is a round brilliant lab-grown diamond, flanked by two pear-cut lab diamonds that taper gently towards the band. The three-stone layout is designed to sit low enough for everyday wear while still giving plenty of light and presence on the hand.

  • Centre stone: 2.01ct lab-grown diamond, round brilliant (E colour, VS2 clarity)
  • Side stones: 2 × pear-cut lab-grown diamonds, approx. 0.734ct total (DEF colour, VS clarity)
  • Total diamond weight: approx. 2.74ct
  • Metal: 18K white gold, rhodium plated for a bright, mirror-like finish
  • Band: Smooth, polished 18K white gold with a comfortable profile for everyday wear
  • Style: Three-stone engagement ring
  • Made to order: Each ring is custom made in your chosen size once you place your order.

Lab-Grown Diamonds

All three diamonds in this ring are lab-grown, created using advanced technology that replicates the natural diamond-forming process. They share the same physical, chemical and optical properties as mined diamonds, with a more modern and considered approach to sourcing.

  • Real diamonds: Not simulants – true diamonds, grown in a lab.
  • Colour & clarity: E VS2 centre stone with DEF VS side stones for bright, clean sparkle.
  • Value: Allows for a larger carat weight and higher clarity at a more accessible price point.

18K White Gold Setting

The ring is crafted in 18K white gold, chosen for its luxurious weight and durability. Rhodium plating gives the metal a crisp, bright white finish that enhances the fire and brilliance of the diamonds.

The band is designed to sit neatly alongside a wedding band, making it easy to stack and style after the proposal.

Symbolism: Past, Present & Future

Three-stone rings are often chosen to represent your past, present and future together. The centre diamond symbolises the life you are building now, while the two side stones honour where you have come from and everything still to come.

Ring Size & Made-to-Order Timing

This design is custom made to order in your chosen UK ring size. Please select your usual size from the options above. If you are unsure, we recommend having your finger measured by a local jeweller before ordering.

Because each ring is made especially for you, please allow around 3–5 weeks for your ring to be produced and delivered. Lead times can vary slightly depending on how busy our workshop is.

Who This Ring Is For

This ring is ideal if you love the look of a classic round solitaire but want something with a little more presence and meaning. The pear-cut side stones add extra sparkle and width on the finger without feeling overly ornate, keeping the overall look clean, modern and timeless.
