Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 12 x 6 mm marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set halo engagement ring foundation in 10K white gold offers a low-profile design crafted for everyday elegance without excess height.

Each band is hand-finished in our Williamsburg studio, polished to a smooth comfort fit that slips on easily and wears well beneath gloves or alongside stackable rings. The halo setting is engineered to frame the marquise center stone with precision, enhancing its tapered drama while maintaining a secure, balanced feel.

Our commitment to lab-grown diamonds ensures clarity and sparkle with a significantly reduced environmental footprint, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate architectural grace paired with practical wearability, this mounting suits slender to medium finger shapes and complements elongated nail beds. Its subtle profile makes it a versatile choice for daily life and layering.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to tailor the fit and style to your hand.
