Buying guide

What makes a solitaire

A solitaire ring has one center stone and no larger stones beside it. That keeps the eye on the center and makes the ring easy to pair with a wedding band. Some solitaires add small accents in the band or a hidden halo beneath the center for extra sparkle, while keeping the single-stone look from above.

Choosing a shape for a 1ct solitaire ring

Round gives the most sparkle. Oval, pear and marquise are longer, so a 1 carat center in these shapes tends to look larger. Princess, cushion and radiant cuts have squarer outlines, and emerald and Asscher cuts show clean step facets. Heart is a more personal choice.

Band and metal options

  • Plain band: thin or rounded, for a classic look.
  • Pavé band: small lab-grown diamonds along the shank.
  • Hidden halo: small lab-grown diamonds under the center.
  • Cathedral: raised arches with a graduated pavé band.

Gold comes in 10K, 14K or 18K; platinum is the densest, whitest option. The 1 carat figure is the center's weight, and any accents add to the ring's total.

What is the price of a 1 carat solitaire diamond?

In this collection, a solitaire ring with a 1 carat lab-grown diamond center starts from about $950, and most cost between about $950 and $1,100. That price covers the finished ring with the center already set, in the smallest metal option. Platinum, higher gold karats and pavé or hidden-halo bands add to it. Lab-grown diamonds cost far less than natural diamonds of the same size.
