Historically, halo settings became fashionable in the late Victorian and Edwardian eras. Later on, the blue sapphire halo diamond ring was popularized by Lady Diana, since her iconic engagement ring became a symbol of sophistication and luxury.
This model has a traditional design with a central gemstone (e.g. sapphire, ruby, tanzanite, citrine or amethyst) surrounded by diamonds.
It is increasingly chosen and appreciated as an engagement ring.
