Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, lending a subtle drama to the hand. This semi-set solitaire ring frames a 9 x 4.5 mm marquise stone, ready to be paired with your chosen center, nestled in a sleek 14K rose gold band that balances warmth with understated elegance.

Crafted in Williamsburg, Brooklyn, the band features a low-profile setting designed for everyday wear—its smooth edges and secure prongs ensure comfort without sacrificing security. The rose gold’s soft glow complements the marquise’s pointed shape, while the semi-set design invites personal choice and customization.

Each ring reflects Haejin Jewelry’s commitment to ethical craftsmanship, showcasing lab-grown diamonds that offer clarity and brilliance with a smaller environmental footprint. The result is a piece that honors both beauty and responsibility.

Ideal for those who appreciate refined geometry and a ring that fits seamlessly into daily life, this solitaire’s slender band feels light on the finger and pairs effortlessly with stackable bands or wedding bands. Its low profile makes it glove-friendly and unobtrusive for active hands.

Should you need adjustments, resizing is handled with care at our Williamsburg studio, ensuring a perfect fit without compromising the ring’s integrity.
