Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This semi-set halo engagement ring in 18K yellow gold frames a 12 x 6 mm marquise center with a whisper of brilliance, inviting your choice of stone to complete its story.

Crafted with precision in Williamsburg, the band’s warm gold glow complements the marquise’s tapered drama, while the halo setting adds a subtle shimmer that enhances the diamond’s natural fire. The low-profile design ensures everyday comfort, with a smooth finish that feels as intimate as the moment it marks.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and conscience in equal measure. The ring’s slender band suits those who appreciate refined elegance—ideal for stacking or wearing solo, its shape elongates the hand with graceful ease.

Should you need adjustments, resizing is handled delicately in-studio to maintain the ring’s balance and integrity. Whether you visit us in Williamsburg or begin your custom design online, this semi-set invites you to personalize a symbol of enduring affection.
