Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a subtle drama that feels both intimate and bold. This semi-set halo engagement ring in warm 10K rose gold frames an 8 x 4 mm marquise center with delicate pavé, enhancing its graceful taper and drawing the eye along the finger.

Crafted in our Williamsburg studio, the band’s gentle curve and low-profile setting ensure a comfortable fit for everyday wear, while the rose gold’s soft glow complements a variety of skin tones. Each detail is hand-finished and inspected to balance sparkle with durability, making it a refined choice for those who appreciate quiet sophistication.

Our diamonds are lab-grown, offering clarity and brilliance with a lighter environmental footprint. This ring’s slender silhouette suits slender to medium fingers and layers beautifully with other bands, whether for stacking or solo wear.

Should you need a custom size, resizing is available with care to maintain the ring’s delicate proportions. Lead times vary slightly depending on customization but we keep you informed throughout the process.
