Lab-Grown Diamond Engagement Ring

Soft light filters through a cushion-cut diamond’s gentle curves, catching the eye with a quiet, vintage-inspired glow. This semi-set three-stone engagement ring in 18K rose gold frames a 9 x 9 mm center stone, inviting you to select a lab-grown diamond that balances warmth and brilliance.

Handcrafted in Williamsburg, the band’s subtle blush hue complements the cushion’s rounded facets, while the three-stone setting offers a delicate interplay of light and shadow. The low-profile design ensures everyday comfort, with a smooth interior that rests naturally against the finger.

Each piece reflects a commitment to sustainability, featuring ethically sourced lab-grown diamonds that reduce environmental impact without compromising clarity or fire. The rose gold’s soft glow pairs beautifully with the cushion shape’s romantic silhouette, making it ideal for those who appreciate a blend of classic charm and modern craftsmanship.

This ring suits hands that favor a graceful statement—its balanced proportions stack well with wedding bands or stand alone as a poetic symbol of commitment. The semi-set style allows you to personalize the centerpiece, ensuring your ring is as unique as your story.
