Lab-Grown Diamond Engagement Ring

Soft light filters through the gently rounded corners of an 8 x 8 mm cushion diamond, poised to catch the eye with its subtle vintage glow. This three-stone semi-set ring offers a handcrafted foundation in warm 18K rose gold, inviting your choice of center stone to complete its story.

Each band is meticulously shaped in our Williamsburg studio, balancing a refined profile with a smooth comfort fit that rests naturally against the skin. The rose gold shank is carefully finished to a satin sheen, enhancing the diamond’s soft sparkle without overwhelming it.

Crafted with lab-grown diamonds, this piece reflects a commitment to ethical jewelry—minimizing environmental impact while maximizing clarity and brilliance.

Designed for those who appreciate artisanal detail and understated elegance, the low-profile setting pairs beautifully with stacking bands or worn solo. Its gentle curves complement a range of hand shapes, making it a versatile choice for daily wear.

Should you need resizing, our in-studio process ensures a precise fit without compromising the ring’s integrity. Typical lead times accommodate thoughtful customization without rush.
