Sapphire & Diamond Halo RingThis classic halo ring is one to keep forever and beyond. The surrounding halo of sparkly diamonds enhance the brillance of the sapphire and emphasize her beauty. The origin of the Halo ring goes back to the early Georgian era (1714 1837) with mostly round designs. Later on in the Victorian era, oval shapes became popular and were often made with a different stone in the middle to imitate a flower.
