Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone semi-set ring, crafted in warm 18K yellow gold, invites you to select a center stone measuring 9 by 4.5 millimeters—its tapered shape lending a graceful elongation to the finger.

Each band is shaped and polished in our Williamsburg studio, where the artisan’s touch ensures a smooth comfort fit and a low-profile setting that sits close to the skin. The side stones frame the center with balanced precision, enhancing the marquise’s architectural elegance without overwhelming daily wear.

Our diamonds are lab-grown, offering a clarity and brilliance born from sustainable practices that respect both earth and craft.

This ring suits those who appreciate a statement piece that remains wearable—its slender silhouette pairs beautifully with stacking bands or alone as a refined symbol of commitment. The low-profile design slips easily beneath gloves and fits comfortably for everyday life.

Should you wish to adjust sizing or explore stone options, our Brooklyn studio offers personalized consultations to guide your choices with care and expertise.
