Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along the hand with quiet drama. This solitaire semi-set ring offers a refined foundation, crafted from warm 18K yellow gold that invites the cool gleam of your chosen stone to take center stage.

Expertly engineered for everyday wear, the low-profile setting keeps the diamond close to the finger, reducing snagging while maintaining a confident presence. The band’s smooth finish and balanced weight ensure comfort throughout daily life, whether worn solo or paired with complementary bands.

Each piece is thoughtfully crafted in our Williamsburg studio, where precision meets a commitment to sustainability through lab-grown diamonds—clear, ethical, and radiant without compromise.

Designed for those who appreciate subtle sophistication, this mounting suits a variety of hand shapes, especially elongating fingers with its marquise form. Its streamlined silhouette works well under gloves or stacked with other rings, making it a versatile choice for modern wearers.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive service to ensure your ring fits seamlessly.
