Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring invites you to select a center stone measuring 9 by 4.5 millimeters, a shape known for its tapered points and graceful, vintage-inspired presence.

Crafted from warm 18K yellow gold, the band is hand-finished in our Williamsburg studio with a subtle comfort fit that rests lightly against the skin. The low-profile setting balances security with wearability, designed to slip easily beneath gloves or stack alongside other bands without catching.

Each lab-grown diamond offers a clarity and brilliance that honors sustainable practices, reflecting a commitment to ethical jewelry without compromise.

This ring suits those who appreciate a bold yet refined statement—elongating the hand with its architectural form while remaining versatile for everyday wear. The semi-set design allows you to personalize the centerpiece, making it truly your own.

Resizing is available to ensure a perfect fit, and our Brooklyn studio welcomes you to explore the design process in person or online at your convenience.
