Product Description

Round Lab-Grown Diamond 3-Stone Engagement Ring — 1ct Center

A three-stone ring isn't a trend piece. Past, present, future — one center stone flanked by two that hold their own, and one of the few settings that actually earns the cliché. Built on the bench in Woodside with round Lab-Grown Diamonds set in solid 14K gold, so the story costs what it should rather than what a markup says it should.

Three stones, one line of light

A 1ct round brilliant Lab-Grown Diamond sits slightly raised in four prongs, flanked by two matched 0.35ct rounds — 1.35ctw across the three. Every stone is D–F color and VS+ clarity, so the trio reads bright and icy-white from across a room, nothing visible to the eye and no warm tint. There is no halo here doing damage control. The proportions carry the ring and three honest diamonds do the talking.

What a 1ct round actually measures

Your center stone spans roughly 6.5mm face-up and each side stone about 4.5mm, so the three together cover close to 15.5mm of finger. That is the number worth knowing when you are weighing a three-stone against a solitaire: a 1ct solitaire gives you 6.5mm of presence, and this gives you nearly two and a half times the spread for about a third more carat weight. Because the center is a full carat, it ships with its IGI report.

Why the side stones are 0.35ct and not smaller

At 4.5mm the sides sit at roughly 70% of the center's diameter, which is the range where they read as part of the ring rather than as accents someone tacked on afterward. Much smaller and they disappear next to a 6.5mm center; much larger and your eye stops knowing which stone is the point. I match the pair for color and cut before either one goes into a setting, because two side stones that disagree with each other are far more noticeable than one stone that is slightly off on its own.

How it sits with a wedding band

The three stones run in a straight line across the setting and the shank tapers cleanly into it, so a straight wedding band meets the ring without a wedge of daylight between them. Since I make both to order, tell me you want a pair and I will cut them together.

If you want a different center shape

The same three-stone architecture is on the site with an oval center at 1ct, a marquise at 1ct, and a cushion at 2ct with trillion sides.

Made for you in Woodside

Nothing here is sitting in a case waiting for a buyer. Yours is cast, set and finished after you order it, in solid 14K yellow, white or rose gold, nickel-free, cut to your finger rather than sized down to it — 4 through 9 including halves. Made to order in 7 to 10 business days. Ships fully insured in our signature suede pouch with the IGI report, and carries a lifetime warranty on craftsmanship, complimentary resizing within 60 days, and 14 days to return it if it is not right and you have not had it engraved.
