An ornamental fixture having a support structure and a plurality of ornaments mounted to the support structure in a substantially completely spherical arrangement of ornaments. The ornaments may be glass crystal ornaments, for example, octagonal glass crystals, and a light may be mounted within the fixture. The support structure may include an upper support ring and at least one lower support ring vertically spaced from the upper support ring and a plurality of arcuate sector assemblies removably mounted to the upper support ring and the at least one lower support ring. The sector assemblies retain the ornaments to provide a substantially continuous 360-degree array of ornaments. The sector assemblies can also be disassembled from the support structure for maintenance, servicing, relamping, and cleaning of the fixture. For example, the disassembled components of the fixture may be washed in a dishwasher without damaging the ornaments or the support structure.
