Single halo rings feature a center stone surrounded by diamonds or gemstones, which add to its sparkle while providing a buffer of protection.
A double halo ring comes in a variety of styles, with the main concept being that there are two halos surrounding the center stone. This is perfect for more sparkle and even more protection for the center stone.
Triple halo settings are rarer and very elaborate, as they feature three halos encircling the center stone. This type of setting focuses as much on the setting as it does on the center diamond and is very extravagant and glitzy.
Of these three options, double halo settings provide an excellent balance between glamor and simplicity.
