Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points casting delicate shadows along the finger. This 6 x 3.5 mm stone is securely nestled in a 14K rose gold band, where subtle accent stones trace the shank, enhancing the ring’s refined geometry without overwhelming its sleek profile.

Crafted with a low-profile setting, the ring sits comfortably close to the skin, designed for daily wear without catching or shifting. The rose gold is hand-polished to a soft glow, its warmth complementing the diamond’s crisp brilliance. Each detail is inspected in our Williamsburg studio to ensure a seamless balance of durability and elegance.

Choosing a lab-grown diamond means embracing clarity and sustainability—this ring reflects a commitment to ethical jewelry without compromise.

The slender band and modest height make this piece ideal for those who prefer a subtle statement or enjoy stacking with other bands. Its shape naturally elongates the finger, lending a graceful, architectural edge to the wearer’s hand.

Should you need resizing, our in-house artisans accommodate adjustments with care, preserving the integrity of the setting.
