Lab-Grown Diamond Engagement Ring

When sunlight catches the gentle curve of a 14K rose gold band, it warms the skin like a whispered promise. This semi-set engagement ring offers a delicate frame for a round center stone between 4.2 and 4.9 mm—its classic brilliance ready to sparkle with your chosen diamond.

Crafted in Williamsburg, the band’s comfort fit embraces the finger with a subtle taper, designed for everyday wear without intrusion. The six-prong setting balances security with openness, allowing light to dance freely across the stone’s facets. Each ring is hand-finished and inspected in-studio, ensuring a smooth polish and precise symmetry.

Choosing a lab-grown diamond here means embracing clarity and conscience, reflecting a commitment to sustainable luxury without compromise. The warm blush of rose gold complements a variety of skin tones, while the ring’s low profile makes it glove-friendly and stackable alongside wedding bands or meaningful heirlooms.

Should you need resizing, our Brooklyn studio offers attentive adjustments to ensure a perfect fit. Lead times vary slightly depending on customization but are communicated clearly from the start.
