Buying guide

Picking a center shape at 1.5 carats

Carat weight measures mass, so shapes of the same weight look different in size. Ovals, pears and marquise centers are long and shallow, so they cover more of the finger and look larger. Round and cushion centers show the most sparkle. Emerald and Asscher cuts have step facets that show clean flashes of light and a calm, mirror-like look. Princess and radiant centers give a square or rectangular outline with brilliant sparkle, and a heart reads clearly at this size.

How the band changes the ring

  • Plain band: a thin band makes the center look larger; a rounded band feels smooth on the finger.
  • Pave band: small lab-grown diamonds run along the top of the band.
  • Hidden halo: a ring of small stones sits under the center, seen from the side.
  • Cathedral: arches lift the center over a graduated pave band.

Metal and karat

Platinum is naturally white and the densest choice. Gold comes in 10K, 14K or 18K white, yellow or rose gold; higher karats hold more gold and cost more. Prices start at about $1,250 with the 1.5 carat lab-grown diamond center included. Pave, hidden halo and cathedral styles add small accent stones beyond the center.
