Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand with subtle drama. This semi-set halo engagement ring foundation in warm 14K yellow gold offers a handcrafted canvas for a 10 x 5 mm center stone, designed to amplify brilliance through a delicate frame of smaller diamonds.

Each band is shaped and finished in our Williamsburg studio, where the artisan’s touch ensures a smooth comfort fit and a low-profile setting that slips easily beneath gloves or alongside stackable rings. The halo setting, once completed with your chosen marquise diamond, will enhance the stone’s signature pointed elegance and elongate the finger with refined geometry.

Our commitment to lab-grown diamonds means your ring carries a clarity and sparkle born from sustainable innovation, reflecting a modern approach to ethical jewelry without compromise.

Ideal for those who appreciate architectural lines paired with handcrafted warmth, this semi-set ring invites personal choice while promising everyday wearability and a balanced hand feel.
