A trilogy engagement ring, also called a three stone ring, sets three diamonds side by side: a centre stone flanked by two smaller ones. It is one of the most meaningful designs you can choose, and every ring is handmade by our family workshop in 100% recycled, hallmarked platinum or 18ct gold, with a certified centre diamond.

What Does a Trilogy Ring Mean?
The three stones are often said to stand for your past, your present and your future together. Others see them as friendship, love and fidelity. Whichever story you prefer, a trilogy ring says more than a single stone, and the side diamonds add width and sparkle on the hand.
Choosing Your Diamond Shapes
Most trilogy rings match three stones of the same shape, with the centre diamond the largest. A round brilliant trilogy gives the most sparkle. Oval, emerald and princess cuts create a longer, more modern line across the finger, and pear or heart side stones can frame a round centre for a softer look. Every centre diamond is independently certified.
Getting the Proportions Right
The side stones are usually between a third and a half of the centre stone's carat weight. Larger side stones give a bold, even row of three; smaller ones let the centre diamond lead. We are happy to talk you through the balance before you choose.
Platinum or Gold?
Platinum is naturally white and very hard-wearing, which makes it the most secure setting for three diamonds worn every day. 18ct white, yellow and rose gold offer a warmer choice and a lower price. Read White Gold vs Platinum: The Ultimate Showdown for a side-by-side comparison.
Pair It With a Matching Band
Trilogy rings sit beautifully with a shaped or diamond-set wedding band. See our bridal ring sets, or design your own trilogy with the Ring Maker.
