Three-Band Combined Gold Ring Set with Ruby and Diamonds

This jewelry piece is a three-piece ring set, likely fused together or worn as a single unit, crafted from yellow gold. The central ring features a prominent three-stone past-present-future setting, anchored by an oval-shaped faceted ruby of a deep pinkish-red hue. Flanking the center stone are two brilliant-cut colorless gemstones, which appear to be diamonds. This central band is nestled between two matching outer bands, each featuring a channel-set row of smaller princess-cut or square-shaped colorless gemstones, presumably diamonds. The construction suggests a modern classic style popular from the late 1990s to the early 2000s. The metal displays a polished finish with some visible light surface scratches and minor dulling characteristic of regular wear. The stones appear securely set, though the central ruby shows some internal inclusions under magnification. The craftsmanship is commercial fine jewelry grade, characterized by thick metal bands and precise channel setting. No maker's marks or hallmarks are clearly visible in the image, but the color density suggests 14k or 18k yellow gold.
