Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as an 8 x 4 mm marquise diamond catches the light with its tapered brilliance. This semi-set solitaire ring in warm 14K rose gold offers a refined silhouette, designed to sit close to the hand without excess height.

Crafted in Williamsburg, the band is smoothly finished with a comfort fit, ensuring ease for everyday wear. The low-profile setting balances security with understated elegance, allowing the marquise’s distinctive shape to command attention without catching on fabric.

Each lab-grown diamond is selected for clarity and ethical provenance, reflecting a commitment to sustainable fine jewelry. The rose gold’s gentle blush complements the stone’s fiery facets, creating a harmonious glow.

Ideal for those who appreciate architectural form and subtle drama, this solitaire suits slender to medium finger sizes and layers effortlessly with stacking bands or wedding rings. Its streamlined design makes it glove-friendly and practical for daily life.

Should you need resizing, our Brooklyn studio handles adjustments with care, typically within a few weeks to maintain the ring’s integrity.
