Trilogy Lab Grown Diamond Engagement Rings
A trilogy ring sets three lab grown diamonds side by side, a centre stone with one to each shoulder, often read as past, present and future. Every Luma trilogy is made to order in our Hatton Garden workshop around IGI certified diamonds, from £830. We price it directly, without the retail markup.

How much does a trilogy lab grown engagement ring cost?
A trilogy setting starts at £830 in 9k gold at Luma, with 14k gold, 18k gold and platinum above that, and we price your certified diamonds separately on top. A trilogy costs more than a solitaire for the obvious reason that you are buying three stones rather than one, and the mount has to hold all three in line.
The usual way to keep it sensible is to take the centre stone at the size you actually want and drop the shoulder stones a step smaller. The eye reads the centre first, so a slightly smaller pair either side costs noticeably less and changes very little about how the ring looks on the hand.

Why a trilogy
A trilogy puts three diamonds in a line, a centre stone flanked by two smaller ones. It carries more total sparkle than a solitaire and a meaning many people like, the three stones standing for past, present and future. The side stones also make the centre feel larger without a single very large diamond.
How to build yours
Each Luma trilogy starts as a setting. You choose the centre shape, the diamonds and the metal. The side stones can be round, pear or tapered to suit the look. Good places to start are the Thessa and the Mirella. You can see the wider range on the engagement rings page.
The diamonds
Every stone is a lab grown diamond, the same material as a mined one with the same hardness, clarity grades and sparkle, independently certified. The three diamonds are matched so they sit evenly. You see the exact centre diamond and its certificate before anything is set.
Metals and pricing
Choose 9k or 18k gold in white, yellow or rose, or platinum. Our trilogy rings are made to order from £775, and because we sell direct you pay for the ring and the diamonds, not a shopfront on top.
Made in Hatton Garden
We design and make in Hatton Garden, the centre of the London jewellery trade. If you want to compare trilogy styles and centre shapes in person, book a consultation and a jeweller will take you through the options. There is no shop floor to browse, just a quiet room and the people who make the rings.
