Lab-Grown Diamond Engagement Ring

When light catches the delicate curves of a heart-shaped diamond, it feels like a quiet promise suspended in time. This semi-set engagement ring invites you to choose a 10 x 10 mm center stone, its tender silhouette poised to capture both brilliance and sentiment.

Crafted in warm 18K yellow gold, the band embraces a five-stone arrangement that balances intimacy with subtle sparkle. Each setting is meticulously hand-finished in our Williamsburg studio, ensuring a low-profile silhouette that rests comfortably for daily wear without sacrificing presence.

Our commitment to lab-grown diamonds means your ring carries clarity and conscience, reflecting a sustainable approach to fine jewelry. The heart shape’s soft lobes and pointed tip lend a romantic geometry that elongates the finger gracefully, while the five-stone design adds a gentle rhythm of light.

This ring suits those who appreciate a blend of classic emotion and modern craftsmanship—ideal for stacking or wearing solo with ease. Its comfort fit and modest height make it glove-friendly and resilient for everyday moments.

Should you wish to adjust the band size, resizing is handled expertly in-house to maintain the ring’s integrity and finish. Typical lead times for custom center stones and final assembly are shared transparently during your consultation.
