Lab-Grown Diamond Engagement Ring

Sunlight catches the softly rounded corners of a 5x5 mm cushion diamond, its gentle glow framed by two smaller stones that balance warmth and brilliance. This three-stone semi-set ring invites you to choose a center stone that reflects your story, nestled in a 14K white gold band meticulously shaped for everyday grace.

Handcrafted in our Williamsburg studio, the band’s subtle curvature and polished finish ensure a comfortable fit that sits low against the finger, ideal for stacking or wearing solo without catching. The prong setting is engineered to secure your chosen cushion diamond while allowing light to dance freely across its facets, revealing the stone’s signature soft vintage glow.

Each lab-grown diamond offers clarity and sparkle with a smaller environmental footprint, aligning with a quiet commitment to ethical jewelry. The cool tone of 14K white gold complements the cushion’s warmth, creating a harmonious balance that suits a variety of skin tones and personal styles.

Designed for those who appreciate artisan detail and modern wearability, this ring adapts seamlessly to daily life—whether layered with other bands or standing as a singular statement. Resizing is available to ensure a perfect fit, with care instructions provided to maintain the metal’s sheen and the stone’s brilliance.
