Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that dances with every movement. This three-stone semi-set ring features a 10 x 5 mm marquise center, poised to frame your chosen lab-grown diamond with delicate precision.

Crafted from warm 14K rose gold, the band is shaped and finished in our Williamsburg studio with a subtle comfort fit that rests gently against the finger. The three-stone setting balances architectural elegance with everyday wearability, its low-profile design ensuring ease beneath gloves or layered with other bands. Each prong is hand-formed and inspected to secure your stone while allowing light to flood the facets.

Our lab-grown diamonds offer the clarity and fire of mined stones with a fraction of the environmental impact, reflecting a commitment to ethical jewelry without compromise.

This ring suits those who appreciate refined craftsmanship and a statement silhouette that elongates the hand. Its versatile profile invites stacking or solo wear, adapting seamlessly to daily life.
