Three Stone Lab Diamond Engagement Rings

A three stone engagement ring sets a center lab grown diamond between two side stones. Many people say the three stand for past, present and future. Others simply love the width and sparkle. Three stone rings are priced from $2,690, with an IGI or GIA report for the center stone.

How a three stone ring looks

The side stones frame the center and spread the ring across the finger. The result looks generous and balanced. A three stone ring with a 1.5 carat center and two smaller sides feels much fuller on the hand than a solitaire of the same center size.

Because the side stones add width, the style suits medium and larger hands especially well. On slim fingers, smaller side stones keep the look light. We keep samples in a few proportions at the showroom so you can see which balance suits you.

Side stone pairings

• Round with rounds: classic and bright, easy to match.
• Emerald with trapezoids or baguettes: clean, architectural lines.
• Oval with pears: soft curves that lengthen the finger.
• Radiant or cushion with half moons: a bold, tailored look.

As a rough guide, side stones of about a third to a half of the center’s weight look balanced. Larger sides make the ring read as a row; smaller sides keep the center in charge. Browse emerald cut, oval and round rings for center ideas.

Matching the stones

All three stones should match in color, so none looks warmer than the others. Clarity can differ slightly on the side stones without being seen. Cut matters most on the center. Our IGI report guide shows what to check on the center stone’s report, and we can show you the side stones under the loupe.

With lab grown diamonds, the side stones cost much less than mined ones, so three stone rings are within reach at sizes that used to be rare.

Settings and wedding bands

Three stone rings sit wider, so the setting needs to be comfortable. A low basket or shared prongs keep the profile neat. Pointed side stones such as pears need tip protection. Most straight wedding bands sit well next to a three stone ring; a slightly curved band works if the stones sit low.
