Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle, tapered sparkle that draws the eye along the finger’s natural line. This solitaire semi-set in 18K yellow gold offers a refined foundation for a 6 x 3.5 mm center stone, designed with a low-profile setting that balances elegance and everyday practicality.

Crafted in Williamsburg, the band’s smooth finish and precise prong placement ensure comfort and security, allowing the diamond’s shape to take center stage without excess height or bulk. The yellow gold’s warm glow complements the marquise’s dramatic form, creating a harmonious contrast that feels both modern and enduring.

Each piece reflects Haejin Jewelry’s commitment to ethical sourcing, featuring lab-grown diamonds that combine clarity and sustainability without compromise. The semi-set format invites you to select a stone that resonates personally, making this ring a true expression of individual style.

Its slender band and low profile make it ideal for daily wear, fitting comfortably beneath gloves or alongside stackable bands. The marquise shape’s elongation flatters a variety of hand sizes, offering a sleek silhouette that feels light and balanced.

Should you need adjustments, resizing is handled expertly in-studio to maintain the ring’s integrity and comfort. Typical lead times accommodate thoughtful customization without rush.
