Lab-Grown Diamond Engagement Ring

Light catches the marquise’s elongated silhouette, casting a slender beam that dances along the finger’s natural curve. This semi-set solitaire invites you to choose a center stone that echoes your story, framed by an 18K yellow gold band that warms the skin with a soft, familiar glow.

Handcrafted in Williamsburg, the band’s smooth finish and subtle taper ensure a comfortable fit, designed to sit low and close for everyday wear without catching. The classic solitaire setting balances elegance with practicality, allowing the marquise shape’s tapered points to shine with architectural grace.

Each ring is crafted with lab-grown diamonds, reflecting a commitment to ethical jewelry that honors both beauty and sustainability. The clarity and brilliance of these stones are matched by the care taken in finishing every detail by hand.

Ideal for those who appreciate a refined silhouette that elongates the finger, this setting pairs effortlessly with stacking bands or stands strikingly alone. Its low profile makes it glove-friendly and suited to a life in motion.

Should you wish to adjust the band size, resizing is available to ensure a perfect fit. Lead times vary slightly depending on stone selection, and we’re happy to guide you through the process.
