Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond’s sharp points, casting a delicate dance of light across the hand. This semi-set halo engagement ring invites you to select a 7 x 3.5 mm marquise stone, its signature shape lending an elegant, tapered drama that visually lengthens the finger.

Crafted from warm 10K yellow gold, the band is shaped and polished in our Williamsburg studio, where each curve is refined for a smooth, comfortable fit. The halo setting, designed to amplify brilliance, is carefully hand-set with micro pavé diamonds, enhancing the center stone’s presence without overwhelming daily wear. Its low-profile design ensures ease beneath gloves or alongside stackable bands.

Our commitment to lab-grown diamonds means your ring carries a clarity and sparkle born of sustainable innovation, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate artisan craftsmanship and a ring that balances bold geometry with subtle comfort, this piece suits hands seeking a statement that remains wearable every day. The semi-set nature allows you to personalize the center stone, making this ring uniquely yours.
