Lab-Grown Diamond Engagement Rings

The shape sets the personality of the ring. Round brilliants return the most sparkle. Ovals, pears and marquise cuts look larger for their carat weight and lengthen the finger. Emerald and Asscher cuts trade sparkle for long, mirror-like flashes of light. Cushion, radiant and princess cuts sit in between, with soft or crisp corners.

A solitaire keeps all the attention on one diamond. A hidden halo adds a secret row of diamonds under the center stone, seen from the side. A halo frames the center and makes it look larger. Three stone rings add two side diamonds. If she works with her hands, a lower setting or a bezel protects the diamond best.

Both are solid gold. 14K gold is 58.3% gold and a little harder, a practical everyday choice. 18K gold is 75% gold, with a richer color and a slightly higher price. Yellow, white and rose gold come in both.

Every design offers a center diamond from 1 carat, and many go to 5 carats or more. Because lab-grown diamonds cost far less than mined diamonds of the same size, many couples choose a larger stone than they first planned. See the starting price for each carat above.

Every center diamond of 1.00 ct and above is graded by IGI and ships with its report. The report confirms the shape, carat, color, clarity and cut. Smaller accent diamonds are hand-selected and not individually graded.
