Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This semi-set engagement ring invites you to choose a 9 x 4.5 mm center stone, framed by four smaller companions that echo its graceful shape in a quiet dance of light.
Crafted in warm 14K rose gold, the band curves gently with a comfort fit that rests naturally against the skin. The five-stone setting balances presence with subtlety, designed low enough to slip easily beneath gloves or stack alongside a wedding band without crowding.
Each piece is finished by hand in our Williamsburg studio, where expert jewelers refine every prong and polish every surface to a soft glow. The rose gold’s blush tone complements the marquise’s vintage-inspired elegance, while the semi-set design offers a bespoke opportunity to select a lab-grown diamond with clarity and brilliance that honors sustainability.
Ideal for those drawn to romantic geometry and a ring that feels as personal as the story it represents, this setting adapts gracefully to various hand sizes and shapes. Resizing is available to ensure a seamless fit, crafted with care to maintain the ring’s delicate balance.
