Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, evoking a sense of refined drama. This semi-set solitaire mounting in 14K rose gold offers a warm embrace to a 9 x 4.5 mm marquise center, designed with a low-profile setting that sits close to the finger for everyday ease.

Crafted with precision in Williamsburg, Brooklyn, the band’s smooth finish and subtle taper ensure comfort without sacrificing presence. The secure prong setting balances protection with maximum light exposure, enhancing the diamond’s signature brilliance while maintaining a sleek profile that slips effortlessly beneath gloves or sleeves.

Each piece reflects a commitment to sustainability through the use of lab-grown diamonds, marrying ethical clarity with modern craftsmanship. The rose gold’s gentle blush complements the marquise’s fiery facets, making it a versatile choice for those who appreciate both elegance and practicality.

Ideal for wearers seeking a distinctive shape that elongates the hand, this solitaire setting pairs well with stacking bands or stands strikingly alone. Resizing is available to ensure a tailored fit, with typical lead times accommodating thoughtful customization.
