Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise, casting a slender, luminous shadow across the skin. This semi-set engagement ring invites you to choose the centerpiece that will transform its delicate 14K rose gold band into a personal emblem of commitment.

The slender shank, crafted from warm 14K rose gold, curves gently to cradle the marquise stone with a low-profile setting that balances elegance and everyday wearability. Its subtle tapering ensures comfort beneath gloves or alongside stackable bands, while the polished finish reflects soft light with every movement.

Each piece is meticulously hand-finished in our Williamsburg studio, where expert jewelers inspect every detail to ensure a seamless fit and enduring shine. The semi-set design offers flexibility, allowing you to select an 8 x 4 mm marquise lab-grown diamond that aligns with your vision and values.

Our commitment to ethical jewelry is reflected in the clarity and sustainability of lab-grown diamonds, offering brilliance without compromise. This ring suits those who appreciate refined geometry and a silhouette that elongates the finger, perfect for a wearer seeking subtle drama with modern grace.

Should you need resizing or advice on stone selection, our team provides thoughtful guidance tailored to your lifestyle and preferences. Lead times are transparent, with a focus on craftsmanship over speed.
