Watermelon Tourmaline & Diamond Ring | 18K Gold Architectural Elegance

The FOSTIANO Bi-Color Tourmaline & Diamond Ring is a striking fusion of architecture, color, and craftsmanship. Weighing 11.71g, the design centers around a magnificent 15.03ct emerald-cut tourmaline, showcasing a dramatic gradient that shifts from deep green to warm amber. The gemstone’s natural transition of hues feels like watching light move across a horizon—fluid, dimensional, and quietly powerful.

Set in 18K gold, the ring features a sculptural, stepped band accented with 0.405ct of pavé diamonds. These geometric layers frame the tourmaline with a sense of structure and rhythm, creating a dynamic contrast between the gemstone’s organic color flow and the ring’s modern architectural lines. Each diamond is meticulously set by FOSTIANO’s master artisans, highlighting the angles and edges with subtle brilliance.

This ring is designed for those who appreciate bold elegance and distinctive character. The oversized emerald cut amplifies clarity and depth, allowing the bi-color transition to reveal itself differently with every tilt of the hand. Its weight and presence feel intentional—strong, confident, and refined.
