Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in 18K rose gold offers a warm, modern-minimal frame, designed to amplify the stone’s architectural drama without distraction.

Crafted with precision in our Williamsburg studio, the rose gold band is polished to a soft sheen and shaped for comfort, its low-profile setting ensuring everyday wearability. The halo setting, ready to embrace your chosen center, balances brilliance with subtlety, while the secure prong arrangement promises lasting durability.

Each lab-grown diamond reflects a commitment to ethical sourcing and sustainability, offering clarity and fire without compromise. The marquise cut’s distinctive shape elongates the finger, ideal for those seeking a confident yet refined statement piece.

This ring suits hands that appreciate sleek geometry and a design that layers effortlessly with stackable bands or stands alone with quiet strength. Its comfort fit and modest height make it glove-friendly and practical for daily life.
