Gold Ring with Central Oval Stone and Two Side Stones

This is a yellow gold ring featuring a central, oval-cut dark gemstone flanked by two smaller, round-cut lighter stones. The ring has a classic signet or dome-style band that appears to taper slightly towards the back, characteristic of many vintage or antique designs. The primary metal is clearly yellow gold, exhibiting a warm, lustrous tone. The central stone is dark, possibly a black onyx, dark sapphire, or a similar opaque or very dark translucent stone, set horizontally within a raised bezel or flush setting. Its surface reflects some light, indicating it is polished. The two smaller side stones are round and lighter in color, possibly diamonds, white sapphires, or rock crystal, also set flush into the gold band. The overall construction appears solid and sturdy, with the gold forming a smooth, continuous surface around the stones. There are no visible maker's marks or hallmarks discernible from this image alone. The ring shows some minor surface wear consistent with age and use, particularly on the gold's polished areas and potentially on the surface of the central stone, which might exhibit minuscule scratches or abrasions under closer inspection. The style suggests it could be from the mid-20th century or earlier, possibly a men's ring given its robust appearance, or a statement piece for a woman. The craftsmanship appears to be of good quality, with well-integrated stone settings and a smoothly finished gold surface. The stones are well-proportioned to the ring's design, creating a balanced and classic aesthetic.
