Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along its tapered points, creating a subtle drama that feels both refined and distinctive. This semi-set solitaire mounting in 14K white gold offers a sleek, low-profile frame designed to cradle a 10 x 5 mm center stone securely while maintaining a streamlined silhouette.

Crafted in Williamsburg, the band is polished to a soft sheen and shaped for comfort, allowing the ring to sit close to the finger without catching on daily fabrics. The prong setting is engineered for durability and ease of wear, ensuring the diamond’s brilliance remains uninterrupted by bulky metalwork.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact without compromising on clarity or fire. The cool tone of the white gold complements the marquise’s glassy facets, enhancing its architectural elegance.

Ideal for those who appreciate a modern yet understated statement, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or wedding rings. Its low profile makes it glove-friendly and practical for everyday wear.

Should you wish to adjust the fit, resizing is available with careful attention to preserving the ring’s balance and comfort. Typical lead times accommodate the custom nature of your chosen stone and setting.
