Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a subtle, tapered glow that draws the eye along the finger. This semi-set engagement ring foundation is crafted from 18K yellow gold, its warm hue a gentle contrast to the crisp white gold accents that frame the setting with quiet precision.

The low-profile mounting ensures the ring sits close to the hand, designed for everyday wear without catching or discomfort. Each curve is carefully polished to a smooth finish, while the secure prong setting balances protection with maximum light exposure for the 6 x 3.5 mm marquise center stone you select.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable practices, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate refined geometry and a sleek silhouette, this ring complements slender fingers and pairs effortlessly with stackable bands or a wedding band. Its comfort fit and modest height make it glove-friendly and suitable for an active lifestyle.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
