Choosing a lab-grown diamond trilogy ring
Centre stone and side stones
A trilogy ring sets a lab-grown diamond either side of the centre stone. Three matching round brilliants give a classic, even line of sparkle, while contrasting side stones, such as trillion, pear or baguette cuts, frame an oval, emerald, cushion or radiant centre and give the ring a more distinctive outline.
Quality you can check
Every stone we set is a lab-grown diamond, D–F in colour and VS1 clarity or better. Rings with a centre stone of 1.00ct or above come with an individual IGI grading report as standard, at no extra cost.
Size and timing
Every ring is made to your size at no extra cost, including half sizes; measure a ring she already wears with our ring size guide. Rings are made to order in around four weeks, including UK hallmarking where required, and UK delivery is free, tracked and signed for.
