Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set halo ring foundation in 18K yellow gold offers a warm, rich canvas for a 6 x 3.5 mm marquise center stone, designed to amplify the gem’s signature brilliance and slender elegance.

Handcrafted in our Williamsburg studio, the band is meticulously shaped for a smooth, comfort fit that sits low against the skin, ideal for daily wear. The halo setting, once completed with your chosen stone, will frame the marquise with delicate pavé diamonds, enhancing light reflection without adding bulk.

Each piece reflects our commitment to ethical jewelry: the center stone is lab-grown, offering clarity and sparkle with a smaller environmental footprint. This ring suits those who appreciate refined geometry and a subtle vintage nod, especially flattering on slender fingers or when stacked with complementary bands.

Should you need adjustments, resizing is available to ensure a perfect fit. Lead times vary slightly depending on stone selection but we keep you informed throughout the process.
