Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring in 14K yellow gold offers a refined foundation for a 9 x 4.5 mm marquise center, framed by delicate accent stones that enhance its graceful profile without overpowering.

The band is crafted with a low-profile setting, designed to sit close to the finger for everyday comfort and ease of wear. Its smooth finish and secure prongs ensure durability while maintaining a sleek, modern line that complements the diamond’s distinctive shape.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to ethical sourcing and sustainable practices without compromising on visual impact.

Ideal for those who appreciate architectural elegance paired with practical design, this ring’s slender band and subtle accents make it an excellent choice for stacking or wearing solo. Its low profile also fits comfortably under gloves or sleeves, adapting seamlessly to daily life.
