Three stones in a row, each with its own meaning
A trilogy ring is often worn as an engagement ring or to mark a milestone, and the three stones in a row give it a different look than a ring with a single center stone. When choosing, it comes down to three things. The shape of the stones, how large they are altogether, and whether the ring should be in 14K gold or 14K white gold. Here we go through what sets the designs in the collection apart, so you can find the ring that suits the hand and the occasion.
Three diamonds that often stand for past, present and future
A trilogy ring has three diamonds set in a row, where the middle one is typically the largest. The three stones are often interpreted as past, present and future, and that very meaning makes the ring a popular choice as an engagement ring and for milestone wedding anniversaries. Where a solitaire ring gathers all the light in one stone, the trilogy ring spreads the brilliance across three, giving the ring more width and movement on the finger. If you want to compare with other shapes, you'll find them in our solitaire rings and other rings.
Round, oval or petite
The collection comes in three main shapes. The round is classic and reflects a lot of light, and a round trilogy diamond ring carries 2.4 carats spread across the three stones. The oval stretches the finger optically and appears a bit larger at the same weight, and an oval trilogy diamond ring comes in at 1.7 carats. If you want a more discreet look for everyday wear, a petite trilogy diamond ring stays at 0.6 carats. All three shapes are available with both natural and lab-grown diamonds. If you want to see the full range of stones, take a look at our lab-grown diamond rings.
14K gold or 14K white gold
Each shape is available in two metals. 14K gold gives a warm tone that highlights the diamonds with contrast, while 14K white gold has a cool, white sheen that blends more with the stones. If you want to see the oval in the cool look, an oval trilogy lab-grown diamond ring is available in white gold, and the petite is likewise available as a petite trilogy lab-grown diamond ring. Both metals are equally durable for daily wear. Also see our gold and white gold to feel the difference in the tones.
Sizes from 48 to 60
All rings in the collection are available in sizes 48 to 60, so you can find the right fit regardless of shape and metal. If you're unsure about the measurement, our guide to how to measure ring size will help you further. A trilogy ring sits with three stones on top, so it should fit snugly without being tight, to keep the stones sitting upright on the finger.
