Listings typically reference genuine .925 sterling silver and note a 925 hallmark stamp as confirmation of the metal.
Most halo rings are made from .925 sterling silver. Common finishes include rhodium plating and various plated options such as rose-gold, other gold plating, and black plating.
Most listings use cubic zirconia as the center stone, while some pieces feature created or simulated opal.
Some listings specify overall ring widths (for example 14 mm). Matching wedding bands are sometimes listed at about 1.5 mm, and accent stones around the center are commonly about 2 mm.
