Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender beam that dances like a whispered promise across the hand. This halo setting cradles a 12 x 6 mm lab-grown marquise, its pointed silhouette lending a refined drama that feels both intimate and striking.

Crafted in cool platinum, the band’s smooth comfort fit balances the ring’s presence with everyday ease. The halo’s delicate pavé setting enhances brilliance without height, ensuring a low-profile silhouette that slips effortlessly beneath gloves or sleeves. Each facet is meticulously inspected in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are sustainably grown, offering clarity and fire without the environmental cost of mining. This ring suits those who appreciate architectural elegance paired with subtle romance—ideal for slender fingers or as a statement piece in a stack.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s integrity and comfort. Typical lead times reflect the bespoke nature of our craft, ensuring each piece is as unique as the story it celebrates.
