6 Carat Lab-Grown Diamond Rings, grown in light.

A center you notice from across the room. Each 6 carat lab-grown diamond ring in the edit has its six-carat stone fitted at the center and included in its cost. The shape and metal are chosen on the product page. The bands stay narrow, either plain or with pavé shoulders, so the size of the stone does the talking.

Size by shape at six carats

A round 6-carat lab-grown diamond spans roughly 11.7 mm. Oval, marquise and pear shapes trade width for length and look larger from above. Cushion and radiant centers have a fuller, squarer face. Emerald and Asscher cuts, offered on some designs, show broad step-cut facets that read clean and architectural at this weight.

The band beneath the stone

  • Solitaire band: a plain, rounded shank that lets the center stand alone.
  • Pavé shoulders: a line of small lab-grown diamonds on the upper band of most designs.
  • Hidden halo: one design adds small stones under the center that flash from the side.

Choosing a metal at six carats

Platinum keeps its grip on prongs and loses very little metal over decades of wear. White gold gives that silvery color for less. Yellow and rose gold soften the contrast between metal and the lab-grown stone. Band widths sit between about 1.8 and 2.5 mm.

Caring for a six carat ring

Big centers gather more dust and skin oil, which mutes their fire. Once a week, swish it through lukewarm suds and work a soft bristle under the head. Store the ring apart from softer gems, since a lab-grown diamond scratches them as easily as a mined one, and have the prongs checked every six months.

FAQ

6 Carat Lab-Grown Diamond Rings: Common Questions

What is the price of a 6 carat diamond ring?

Rings in this collection, with a 6-carat lab-grown center already set, start at about $4,500, and most are between about $4,650 and $5,050 in the lowest-priced metal. Platinum and pavé raise it. Six mined carats would cost several times this figure.

Is a 6 carat diamond too big?

For everyday wear it is a bold choice, not an impractical one. A round 6-carat lab-grown diamond is close to 12 mm across and covers most of an average finger. For a lower, slimmer look, an emerald cut lays the carats out along the finger instead.

What does a 6 carat diamond ring look like?

It looks like a true statement ring: the center fills much of the finger's width and rises clearly above the band. Above a slim 2.2 mm band, the lab-grown diamond looks larger still. Elongated shapes run toward the knuckle, while cushion and round keep a compact face.
