Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along the length of the finger. This semi-set solitaire ring in 10K yellow gold offers a refined foundation, ready to cradle your chosen stone with precision.

Crafted with a low-profile bezel setting, the band sits close to the skin, minimizing snagging and enhancing comfort for everyday wear. The warm glow of yellow gold is smoothly polished, balancing durability with a subtle sheen that complements the diamond’s sharp geometry.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to sustainable, ethical sourcing without compromise. This ring’s streamlined design suits those who appreciate architectural elegance paired with practical wearability.

Its slender band and low profile make it an excellent choice for stacking alongside wedding bands or other fine jewelry, while the marquise shape naturally elongates the finger for a graceful silhouette. Resizing is available to ensure a precise fit, crafted in-studio with care.
