Marquise Lab Diamond Leaf Engagement Ring Set Solid 14K Yellow

A halo usually circles its stone like a frame. This one grows around it. At the center of this IGI-certified bridal set, a 7x10mm marquise lab-grown diamond rises from a wreath of marquise and round diamond accents arranged as leaves on a vine — all in solid 10K, 14K, or 18K yellow gold, completed by a curved wedding band that nests into the halo’s underside like a stem.

The geometry of a leaf halo

Most halos are rings of identical round stones. Here, marquise-cut accents alternate with rounds so each element reads as a leaf on a branch — a botanical wreath rather than a border. The effect enlarges the center stone’s footprint on the hand while keeping the design unmistakably nature-inspired. If the halo silhouette is what drew you in, you can compare framing styles across our halo engagement rings, or stay within the pointed-oval family in our marquise engagement rings.

A marquise that lengthens the hand

The marquise is the most elongating cut in jewelry: its pointed ends and slender belly stretch the eye along the finger, which is why a 7x10mm stone of approximately 1.5–1.7 carats can look even larger than its weight suggests. Our editorial on why the marquise is the most elongating shape covers the cut’s royal history and how to wear it well.

Certified, grown, and traceable

The center stone is a genuine lab-grown diamond — identical to a mined diamond in chemistry, brilliance, and its Mohs 10 hardness — and the set is IGI certified, so the stone’s grading is independently documented. If you are still weighing origin questions, are lab-grown diamonds real diamonds gives the straight answer, and our lab-grown diamond price guide explains why grown stones deliver more carat for the money. More designs wait in our lab-grown diamond engagement rings.

Solid yellow gold, three ways

Pick your karat from the drop-down: 10K for maximum durability at the friendliest price, 14K for the classic balance of strength and richness (our most popular choice), or 18K for the highest gold content and the deepest warmth. Every option is solid gold through and through, so the color is permanent — nothing to wear away, nothing to turn skin green. The full comparison lives in our 10K vs 14K vs 18K gold karat guide. White or rose gold are available on request, and the curved band pairs naturally with the rest of our curved wedding bands.

Sizing & care

Sizing tools vary slightly between jewelers, so confirm your measurement with our find your size guide before ordering. Each set is made to order in your chosen karat. Care is simple: diamond at Mohs 10 is the hardest gemstone there is, so an occasional wash in warm water with mild soap and a soft brush — paying attention to the underside of the halo, where lotion collects — keeps every facet bright. Store the two rings nested together in their ring box when not worn.
