Solitaire Engagement Rings, Simply Done Well

A solitaire holds one lab-grown diamond on a band with nothing else competing for attention. It is the most enduring engagement ring style for a reason: the shape and sparkle of the center stone do all the talking, and the clean design pairs with almost any wedding band you choose later.

Details That Shape a Solitaire

Small choices change the look. Four prongs show more of the diamond, while six prongs give a round stone a softer outline and extra security. A cathedral setting lifts the stone on graceful arches for height, and a low setting keeps it close to the finger. For an active lifestyle, consider a bezel, a smooth rim of metal that wraps the edge of the diamond and protects it from knocks. Band width matters too: a slim band can make the center stone look larger.

Solitaire engagement rings work with every shape, from round and princess to elongated cuts. Want a touch of extra sparkle? Try a hidden halo, which still looks like a solitaire from the top. Every ring is made to order in 10K, 14K or 18K yellow, white or rose gold, or platinum, with free insured US shipping, 30-day returns, free resizing and a free ring sizer.
