Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated facets of a marquise diamond, it creates a striking silhouette that seems to stretch the hand with elegant drama. This semi-set engagement ring foundation in 18K white gold offers a refined stage for a 10 x 5 mm marquise center stone, its pointed ends balanced by a slender, polished band.

Crafted in our Williamsburg studio, the band’s smooth finish and subtle taper ensure a comfortable fit for daily wear, while the low-profile setting keeps the diamond close to the finger, reducing snagging. Each mounting is meticulously inspected to meet exacting standards before it leaves the bench.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

This ring suits those who appreciate a bold yet graceful statement piece—its slender silhouette complements slender to medium finger sizes and layers beautifully with wedding bands or stackable rings. The semi-set design invites you to select a marquise diamond that resonates personally, making the final ring uniquely yours.

Should you need resizing or guidance on selecting the ideal stone, our Brooklyn studio offers personalized consultations to ensure a seamless process.
