Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along the finger with a subtle, elegant drama. This three-stone semi-set engagement ring features an 8 x 4 mm marquise center, poised to be paired with your choice of side stones for a personalized expression.

Crafted from 18K white gold, the band is shaped with a gentle comfort fit that rests smoothly against the skin, while the low-profile setting ensures everyday wearability without catching. Each element is hand-finished in our Williamsburg studio, where precision meets quiet artistry in every curve and prong.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness.

The slender marquise shape naturally elongates the finger, making this ring ideal for those who appreciate refined geometry and a statement that remains understated. Its semi-set design invites customization, perfect for layering with stackable bands or wearing solo with ease.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the integrity of the setting and comfort of the band.
