Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as an 8 x 4 mm marquise diamond takes center stage, its tapered points drawing the eye with quiet drama. This three-stone semi-set ring in 18K white gold offers a refined silhouette, designed with a low-profile setting that rests comfortably against the skin for everyday wear.

Crafted in our Williamsburg studio, the band’s smooth finish and precise prong work ensure durability without sacrificing elegance. The three-stone arrangement balances visual interest with a streamlined feel, making it ideal for stacking or wearing solo. Each piece undergoes meticulous inspection to meet exacting standards of comfort and craftsmanship.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or brilliance.

This ring suits those who appreciate architectural grace paired with practical design—its low profile slips easily under gloves and fits naturally with active lifestyles. The semi-set format invites you to select a center stone that resonates personally, offering a bespoke touch to your engagement story.

Should you need resizing or advice on care, our team provides thoughtful guidance to ensure your ring remains a lasting companion.
