Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a 5 x 3 mm marquise diamond, casting a slender, elegant shadow across the hand. This semi-set solitaire ring in 14K rose gold offers a refined foundation, ready to cradle your chosen center stone with precision.

Crafted with a low-profile bezel setting, the band sits close to the finger, ensuring comfort for daily wear without sacrificing security. The warm blush of rose gold complements the marquise’s tapered shape, while the smooth finish and subtle tapering enhance its modern silhouette.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact without compromising brilliance or clarity.

Designed for those who appreciate understated sophistication, this setting pairs seamlessly with stackable bands or stands alone as a statement of quiet confidence. Its comfort fit and modest height make it glove-friendly and ideal for an active lifestyle.
