Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This semi-set halo ring foundation in warm 10K yellow gold invites your choice of an 8 x 4 mm center stone, ready to be framed by a halo that amplifies its graceful drama.

Crafted with a low-profile setting, the band curves gently for a comfort fit that slips easily beneath gloves or alongside stackable favorites. Each piece is meticulously finished in our Williamsburg studio, where hand polishing and rigorous inspection ensure a smooth, radiant surface that wears beautifully every day.

Our commitment to lab-grown diamonds means your ring carries clarity and brilliance without compromise, reflecting a sustainable approach to fine jewelry.

The marquise shape’s elongated form visually lengthens the finger, ideal for those who appreciate a blend of vintage allure and modern refinement. Its halo setting enhances sparkle while maintaining a delicate presence, perfect for daily wear or layering with complementary bands.
