Buying guide

How a three stone ring is built

The center sits highest and largest, with a matched pair of side stones beside it. Round side stones give a soft, even line; pear side stones curve in toward the center; baguette and trillion side stones add straight edges that suit emerald and princess centers. Some designs add lab-grown diamond accents in pavé down the band, split the shank, or finish the edges with milgrain for a vintage look. A few use a bezel, a bypass shank or a twisted band.

Choosing the center and side stones

Most designs take the center in round, oval, emerald, marquise, princess, radiant, pear, heart and cushion, and a few in asscher or an elongated old mine cushion. Balance matters: side stones that are too large compete with the center, while very small ones can look lost. A few designs are shown with a fancy pink, yellow, green, blue or black center, which you also choose in the next step.

Metal and price

Nearly every design comes in white gold, and most also come in yellow and rose gold, in 10K, 14K or 18K. Bands run from about 1.8 to 3 mm wide. Settings start under $700, and most cost between about $1,150 and $1,350. That price covers the setting with its side stones; the center is priced when you choose it.

Made to order

Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.

Three Stone Engagement Rings FAQs

What is a 3 stone engagement ring called?

A three stone engagement ring is also called a trilogy or trinity ring. The three stones are often said to stand for a couple's past, present and future. The name covers any ring with a center and two side stones, whatever their shapes, so a round center with pear sides and an emerald center with baguettes are both three stone rings.

Are 3 stone rings popular?

Yes. Three stone rings have been a steady engagement choice for decades and remain popular today. They suit anyone who wants more sparkle than a solitaire without a halo. Classic pairings such as a round with round sides, an oval with pear sides, or an emerald with baguettes keep the style from looking dated, and a slim band keeps it light.

Can a 3 stone ring be an engagement ring?

Yes. The three stone ring is one of the classic engagement ring styles, and every setting on this page is made as an engagement ring, with the center chosen in the next step. It is also a popular anniversary ring, but nothing about the style limits it to that, and it pairs with a wedding band like any other engagement ring.

How much does a three stone engagement ring cost?

Settings here start under $700, and most cost between about $1,150 and $1,350 for the setting with its side stones. The center is priced separately when you choose it in the next step, and its shape, size and grade decide most of the final cost. A three stone ring usually costs more than a solitaire with the same center, since the side stones add to the price.

What wedding band goes with a 3 stone engagement ring?

A curved or contoured band usually fits best, because it follows the side stones and sits flush against the engagement ring. A straight plain band works when the head sits high enough to clear it. Match the metal and karat so the two rings wear evenly, and choose a band of similar width, about 2 mm for most settings here.
