Buying guide

What a 9 carat radiant looks like

The radiant cut combines a square or rectangular outline and clipped corners with brilliant-style facets, so it has the structure of a step cut and the sparkle of a round. At 9 carats the stone is a true showpiece, and the clipped corners make it sturdier than a sharp-cornered square. Lab-grown diamonds have the same hardness, chemistry and fire as mined diamonds.

Picking a style

A solitaire on a thin plain, rounded plain or pavé band keeps the look simple and lets the center dominate. A halo frames the stone in small lab-grown diamonds over a three-row pavé band, and a hidden halo adds sparkle under the center. A three stone ring or marquise and pear side accents widen the ring, and there is also a cathedral style with a graduated pavé band and a vintage-inspired filigree style.

Metal and price

Gold comes in 10K, 14K or 18K in white, yellow or rose. Platinum is dense and naturally white, and its strength suits the prongs holding a center this size. Bands run from about 1.8 to 2.8 mm, and every style offers 2.2 mm. Rings start from about $18,300 with the center included, and most cost between about $18,700 and $18,800.
