Marquise Lab Diamond & Moss Agate Leaf Engagement Ring Set in Solid 14K Yellow Gold (IGI Certified)

One certified diamond, one wild stone. This bridal set pairs an IGI-certified 7 x 10 mm marquise lab-grown diamond — framed by a botanical halo of smaller lab diamonds — with a marquise moss agate ring worn as the wedding band, its natural stones nestled among sculpted golden leaves. Both rings are made to order in solid 10K, 14K, or 18K yellow gold.

A certified diamond at the center

The center stone is a lab-grown diamond — a real diamond in every measurable way, with the same crystal structure, brilliance, and 10-on-the-Mohs-scale hardness as a mined one. It arrives IGI certified, which means an independent gemological laboratory has graded and documented the stone, so what you are buying is verified rather than promised. If certification standards are new territory, our comparison of IGI vs GIA certification explains what the report covers — and if the bigger question is whether grown diamonds are the real thing, start with are lab-grown diamonds real diamonds.

The marquise cut earns its place here twice over: it maximizes face-up size, so the diamond wears larger than its carat weight suggests, and its pointed, leaf-shaped outline ties the stone into the botanical language of the whole set.

The moss agate band: nature answering back

Where the engagement ring is precise and certified, the band is deliberately untamed. Natural moss agate stones sit among sculpted leaves on a vine-like band, and the green, branching inclusions inside each stone formed on their own — tiny sealed landscapes no lab could specify. Because the patterns are natural, your band will be one of a kind, close to the photographs but never identical.

That contrast is the design's argument: modern certainty on one hand, wild growth on the other, worn together. Moss agate's long association with growth and renewal — explored in our guide to moss agate meaning — makes it a fitting counterpart to a stone chosen for permanence.

Solid yellow gold, in the karat you choose

Both rings are made in solid yellow gold, selected from the drop-down:

• 10K — the most durable and most affordable option.
• 14K — our default and most popular: the classic balance of warmth and strength.
• 18K — the highest gold content and the deepest golden color.

Every karat is solid gold all the way through, so the color is the metal itself — permanent by nature. Our 10K vs 14K vs 18K karat comparison guide breaks down the differences.

Sizing & care

Select your size from the drop-down; both rings are made in the size you choose. If you have never been measured, our ring size guide walks you through it in a few minutes.

The diamond ring is as low-maintenance as fine jewelry gets — diamond is the hardest gemstone there is. The moss agate band deserves slightly gentler treatment: remove it for heavy manual work, avoid hard impacts and harsh chemicals, and clean both rings with warm water, mild soap, and a soft brush. Skip ultrasonic cleaners on the agate band, and dry everything with a lint-free cloth.
