Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a 6 x 3.5 mm marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring in 10K white gold offers a refined foundation, ready to cradle a center stone that balances bold geometry with delicate sparkle.

Crafted with a low-profile setting, the band sits close to the finger, minimizing snagging while maximizing comfort for daily wear. The halo’s petite pavé diamonds frame the marquise shape, enhancing brilliance without adding bulk. Each curve and prong is meticulously finished in our Williamsburg studio, ensuring a smooth feel and lasting durability.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry—clear, sustainable, and traceable without compromise on radiance.

This ring suits those who appreciate architectural elegance paired with practical design. Its slender band and subtle height make it ideal for stacking or wearing solo, while the marquise shape visually elongates the hand with a confident, modern edge.

Should you need resizing or prefer a different center stone, our in-studio consultations provide personalized guidance and flexible timelines.
