Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its pointed ends lending a refined silhouette that feels both bold and elegant.

This semi-set solitaire ring features a 10K yellow gold band designed with a low-profile setting that hugs the finger comfortably, ideal for daily wear. The mounting awaits your choice of a 10 x 5 mm marquise center, allowing for a personalized selection that balances striking presence with practical wearability. Each band is meticulously crafted and hand-finished in our Williamsburg studio, ensuring smooth edges and a comfort fit that slips on effortlessly.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness.

The slender yellow gold shank complements the marquise shape’s elongated form, flattering a variety of hand sizes and making it a graceful choice for stacking or solo wear. Its subtle profile fits easily beneath gloves or sleeves, designed for those who appreciate understated sophistication.

Should you need resizing, our in-house artisans provide precise adjustments to maintain the ring’s integrity and comfort.
