Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise diamond, its tapered points drawing the eye along a delicate halo of shimmering pavé. This 6 x 3 mm center stone, set in cool 14K white gold, balances bold geometry with refined craftsmanship.

Each ring is meticulously handcrafted in our Williamsburg studio, where the halo setting is carefully aligned to enhance the marquise’s signature brilliance without adding bulk. The low-profile mounting ensures a comfortable fit beneath gloves or daily wear, while the smooth band curves softly against the finger.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and ethical origin, offering a conscious alternative without compromise on sparkle.

Designed for those who appreciate architectural elegance with a subtle vintage nod, this ring pairs beautifully with stackable bands or stands confidently on its own. Its slender silhouette suits a range of hand sizes, especially elongating shorter fingers.

Should you need a custom adjustment, resizing is available to ensure the perfect fit without disrupting the ring’s delicate balance.
