Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that draws the eye along the finger’s natural line. This semi-set engagement ring invites you to select a 9 x 4.5 mm marquise center stone, whose tapered points and graceful curve evoke a quiet confidence and architectural clarity.

Crafted in 14K yellow gold, the mounting features delicate accent stones that enhance the diamond’s sharp geometry without overwhelming it. The band’s low-profile setting ensures a comfortable fit for daily wear, while the polished finish reflects Brooklyn’s artisanal attention to detail. Each ring is hand-finished and inspected in our Williamsburg studio, where precision meets subtlety.

Our commitment to ethical jewelry is reflected in the use of lab-grown diamonds, offering exceptional clarity and brilliance with a reduced environmental footprint.

Designed for those who appreciate modern minimalism, this ring’s slender proportions and structured accents suit slender to medium finger sizes and stack beautifully with other bands. Its low profile makes it glove-friendly and ideal for an active lifestyle.

Should you need resizing or guidance on selecting the perfect marquise stone, our Brooklyn studio team is happy to assist with personalized advice and timely craftsmanship.
