RINGS MADE TO ORDER

Lab Grown Diamond Engagement Rings

Our lab grown diamond engagement rings, also called lab created or lab made, come in every classic shape and setting. Real diamonds, Excellent cut and VVS-VS clarity, made to order.

A lab grown diamond is a real diamond, grown in a lab instead of mined. It has the same hardness and sparkle as a mined diamond, and a standard diamond tester reads it as a diamond. Ours are grown with CVD technology and chosen to one standard: Excellent cut and VVS-VS clarity, with white diamonds in the D-E-F colorless range.

Lab grown diamond engagement rings by shape

A round brilliant returns the most light and suits almost any setting. Oval, pear and marquise diamonds spread their weight along the finger, so they look larger than their carat weight suggests. Our Dutch marquise keeps that long outline but has six straight sides in place of two curves. Emerald and radiant cuts have clean rectangular lines, and an Asscher cut has the same calm look in a square. For color, see our fancy colored lab grown diamond rings in yellow, pink and green.

Settings, metals and carat weights

A solitaire keeps the focus on one stone. A halo adds a ring of small diamonds around it, and a hidden halo sets them underneath, where they show from the side. A three stone ring sets three diamonds in a row, a toi et moi ring sets two side by side, and an east west setting turns a long stone sideways across the finger. For old world detail, see our vintage lab grown diamond rings.

Choose 9K, 14K or 18K solid gold in white, yellow or rose gold. Platinum and 925 sterling silver are also available. Many designs come in more than one carat weight, so you can also shop by size: 1 carat, 1.5 carat, 2 carat, 3 carat, 4 carat or 5 carat.
