Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that both sharpens and softens the hand’s natural lines. This semi-set solitaire ring in 18K white gold offers a refined foundation for a 12 x 6 mm marquise center, designed to showcase the stone’s tapered drama without distraction.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease under gloves or alongside other stackable pieces. The polished white gold shank is meticulously finished in Williamsburg, ensuring a smooth, comfort-fit experience that balances durability with elegance.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry that respects both the earth and your values.

Ideal for those who appreciate architectural lines and a confident presence, this mounting suits slender to medium finger sizes, allowing the marquise shape to elongate and flatter the hand naturally.
