Lab-Grown Diamond Engagement Ring

Light catches the elongated curves of the marquise shape, casting a subtle, graceful sparkle that seems to stretch across the finger. This semi-set engagement ring invites you to choose a center stone that will become the quiet centerpiece of your story.

Crafted from cool 14K white gold, the mounting features a delicate solitaire setting designed with a low profile to rest comfortably against the hand. The slender prongs cradle the stone securely while allowing maximum light to pass through, enhancing brilliance without bulk. Each piece is meticulously finished and inspected in our Williamsburg studio to ensure a refined surface and lasting wearability.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, offering clarity and beauty with a smaller environmental footprint.

Ideal for those who appreciate a sleek, modern silhouette, this setting suits a variety of hand shapes and sizes, especially elongating fingers with its tapered marquise form. Its subtle height and slim band make it easy to stack or wear alone, fitting seamlessly into daily life and special moments alike.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly.
