Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger as a 5 x 3 mm marquise diamond catches the light with a refined, tapered brilliance. This semi-set engagement ring frame in 14K white gold offers a sleek, low-profile silhouette designed for everyday wear, with delicate accent settings that enhance the stone’s distinctive shape without overwhelming it.

Crafted in Williamsburg, Brooklyn, the band is expertly finished for a smooth comfort fit, ensuring it sits close to the hand without catching. The setting’s precision balances security with elegance, allowing the marquise center to become the focal point while maintaining a streamlined profile ideal for stacking or solo wear.

Each piece embraces lab-grown clarity, reflecting a commitment to sustainable luxury without compromise. The cool white gold tone complements the marquise’s elongated form, while the subtle rose gold accents add a quiet warmth visible only upon close inspection.

This ring suits those who appreciate architectural grace paired with practical design—its low profile and secure mounting make it glove-friendly and resilient for daily life. Whether paired with a wedding band or worn alone, it adapts seamlessly to personal style.
