Modern Lab-Made Trilogy Engagement Ring

Modern in style, the Trieste three-stone lab-made diamond engagement ring benefits from swirling twisted shoulders and six-claw settings securely holding each diamond diagonally across the finger. Available in a choice of metal options and total carat weights from 0.50cts, 0.75cts and 1ct. The diamonds are graded G Colour VS Clarity for perfect whiteness and sparkle. Each ring will get perfectly crafted to order by our artisanal mounters and setters to your exact specification taking around 4-5 weeks, after which we will personally gift wrap it in our luxurious bespoke packaging. The parcel gets dispatched with a secure courier on a next-day service in the UK or just a few days for overseas orders.

Discover what's inside the box

When we send your parcel to USA, we securely wrap the secure outer box in a plain white outer wrapping. Inside you will discover a solid outer box containing a presentation box with engagement ring with an additional pocked ring box. All documents including certification are enclosed within the additional document wallet located in the separate section of the main box. We pride ourselves on luxurious packaging as part of your experience.
