Nine-by-nine-millimeter free-form blue turquoise sterling silver modern cross earrings - the Southwest cross earring that uses free-form turquoise to give the cross motif an organic, natural-material character that distinguishes it from conventional cross jewelry. Free-form turquoise means each stone has a shape determined by the natural material rather than a standardized cut, making each pair unique in exactly the way genuine natural material always is. Composite turquoise. Sterling silver cross setting.
