18 Karat White Gold Ruby and Diamond Halo Collar Necklace

A ruby framed by a diamond halo anchors this 18 karat white gold collar necklace, presenting a streamlined, close-to-the-neck silhouette. The halo arrangement concentrates brilliance around the center stone, emphasizing a clean, symmetrical focal point within a sleek collar profile. Crafted in solid 18k white gold with a polished finish, the centerpiece features securely set diamonds around the ruby for crisp geometry and visual precision. The collar construction is designed for balanced drape and a smooth interior contour, keeping the halo focal steady and prominent against the neckline.
