Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances with quiet elegance. This semi-set engagement ring invites you to select a 6 x 3 mm marquise stone, its tapered points drawing the eye along a graceful arc.

Crafted from warm 10K yellow gold, the slender band is shaped for comfort and daily wear, its smooth finish reflecting the artisanal care poured into every curve. The low-profile setting balances security with subtlety, allowing the diamond’s unique shape to take center stage without overwhelming the hand.

Each lab-grown diamond offers clarity and brilliance with a lighter environmental footprint, aligning with a mindful approach to fine jewelry. The solitaire design suits those who appreciate refined simplicity and the romantic drama of a marquise cut, which naturally elongates the finger and complements slender hands.

Designed to pair effortlessly with wedding bands or stackable rings, this setting adapts to your evolving style. Resizing is available to ensure a perfect fit, and the semi-set format means your chosen diamond will be expertly set in-studio, tailored to your vision.
