Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to stretch beyond the finger. This three-stone semi-set engagement ring in 18K yellow gold invites you to choose a center stone that balances boldness with refined grace.

Crafted with a low-profile setting, the gently curved band offers a comfortable fit that rests naturally against the skin. Each side stone is carefully positioned to enhance the marquise’s tapered drama, while the polished finish reflects the warm glow of the gold beneath. The semi-set design allows for a personalized selection of a 10 x 5 mm marquise diamond, ensuring your ring is uniquely yours.

Our commitment to ethical jewelry is reflected in the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint. This ring suits those who appreciate a statement piece that remains wearable daily, its slender band ideal for stacking or pairing with a wedding band without bulk.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with care in our Williamsburg studio. Lead times vary depending on stone selection, and we’re happy to guide you through the process.
