Women's Solitaire Engagement Rings

You can shop lab diamond solitaire rings at Leonids. Consider Nina for a pear diamond and wave band, Aria for a round four-prong solitaire, or Ivy for an emerald-cut bezel design. Choose your metal and center-stone size, then review the complete ring price, delivery estimate, and return terms.

Start with the diamond’s length and width in millimeters. Nina offers a 0.75 carat pear center diamond, while Aria offers a 1 carat round. Compare their measurements and photos with your ring size. Then check the band width and setting height to find the smaller look you prefer.

No. A smaller center diamond changes how much space the stone covers. A thin band has a narrower metal band. A low-profile setting holds the diamond closer to your finger. Ring size determines fit. Check each measurement separately, since a small diamond can still sit in a tall setting.

Yes. The Nina, Aria, and Ivy products linked here are complete rings with a lab grown center diamond and setting. Check the price for your selected metal and diamond size, along with any custom or rush charges. Compare complete ring prices separately from loose-diamond or setting-only quotes.

No. Solitaire engagement rings are still one of the most popular choices for couples. In The Knot's 2026 study of more than 10,000 couples, solitaire settings made up 38% of the rings selected.

There is no one best shape for every solitaire engagement ring. Round diamonds give a bright, classic look. Oval, pear, and marquise diamonds look longer on the finger. Emerald and Asscher cuts give a clean, step-cut look.Source: GIA 2025 Diamond Shape Guide. Rapaport 2026 Survey Summary.

Oval, marquise, and pear diamonds can look larger than a round diamond of the same carat weight because their elongated outlines cover more of the finger. Compare the millimeter measurements and length to width ratio instead of judging visible size by carat weight alone. Source: GIA 2025 Guide to Making a Diamond Look Bigger.

There is no perfect carat size for every solitaire engagement ring. The Knot’s 2026 study found that lab grown diamond center stones averaged 2 carats, but an average is not a buying rule. Compare your budget, diamond measurements, hand size, band width, and setting height before choosing. Source: Rapaport and The Knot 2026 Engagement Ring Data.

Four prongs cover less of a round diamond and create a more open look. Six prongs provide more contact points, follow the diamond’s round outline, and offer more security. Pear and marquise diamonds may also need protective prongs around their pointed tips. Source: GIA 2025 Round Diamond Setting Guide.

It depends on the height and shape of the solitaire setting. A higher setting often leaves room for a straight wedding band, while a low basket may need a curved or contour band. Choose a lab grown diamond wedding band that follows the setting and gives you the finished bridal set you want. Source: The Knot 2025 Low Profile Ring Guide. Brides Engagement Ring Setting Guide.
