Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of fire and shadow. This semi-set engagement ring foundation in warm 14K yellow gold invites your choice of a 5 x 3 mm center stone, poised to become a singular expression of intention.

Handcrafted in Williamsburg, the slender band curves gently with a comfort fit, designed for everyday wear without catching or crowding. The low-profile setting balances presence with subtlety, allowing the diamond’s unique shape to elongate the finger gracefully.

Each lab-grown diamond offers a clarity and brilliance born from sustainable innovation, reflecting a commitment to ethical jewelry without compromise.

Ideal for those who favor refined minimalism and a romantic silhouette, this mounting suits a hand that appreciates both modern geometry and timeless craftsmanship. Its slender shank layers effortlessly with other bands or stands alone as a quiet statement.

Resizing is available to ensure a precise fit, with careful finishing and inspection completed in our Brooklyn studio.
