Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger’s natural line. This semi-set halo ring foundation in 10K white gold offers a refined stage for a 5 x 3 mm marquise center, designed to balance brilliance with a subtle profile.

Crafted with precision, the low-profile setting ensures the ring sits comfortably beneath gloves and daily wear, while the halo mount promises added sparkle without bulk. The 10K white gold band is polished to a smooth finish, engineered for durability and ease of resizing.

Each lab-grown diamond is chosen for clarity and ethical sourcing, reflecting a commitment to sustainability without compromise. The marquise shape lends a distinctive elegance, elongating the finger and pairing seamlessly with stackable bands or a wedding band.

Resizing is straightforward, handled in-studio with care to maintain the integrity of the setting. Whether designed in our Williamsburg workshop or through our online consultation, this semi-set ring invites personal expression with your chosen center stone.
