Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This semi-set solitaire ring in 10K yellow gold offers a refined foundation for a 7 x 3.5 mm marquise center, ready to showcase your chosen stone’s brilliance.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease under gloves or alongside other rings. The smooth, polished shank balances durability with delicate presence, while precise prong placement secures the stone without excess metal obscuring its shape.

Each piece reflects Haejin Jewelry’s commitment to ethical sourcing, featuring lab-grown diamonds that combine clarity with sustainability. The warm yellow gold complements the marquise’s vintage-inspired form, making it a versatile choice for those who appreciate subtle statement and modern craftsmanship.

Designed for hands that value both elegance and practicality, this mounting suits slender to medium finger sizes and pairs effortlessly with stackable bands or wedding rings. Its streamlined profile ensures it remains unobtrusive during daily wear.
