Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set engagement ring foundation in warm 10K rose gold frames a halo setting, designed to amplify the stone’s striking geometry with a delicate circle of pavé accents.

Crafted in our Williamsburg studio, the band is polished to a soft sheen and shaped for comfort, sitting low enough to slip easily beneath gloves or stack alongside a wedding band. The halo setting balances modern minimalism with structural clarity, offering a confident yet refined profile that complements the marquise’s dramatic presence.

Each piece is finished with meticulous inspection to ensure durability and daily wearability, reflecting our commitment to craftsmanship. The lab-grown diamond center, sold separately, embodies ethical clarity and sustainability without compromise.

Ideal for those who appreciate architectural elegance and a ring that feels as natural as it looks, this mounting invites customization to your preferred center stone size and quality. Resizing is available to ensure a perfect fit.
