Princess-cut cubic zirconia hoop earrings in 18K yellow gold over sterling silver bring one of jewelry's most architecturally precise cuts to the hoop format. The princess cut - a square brilliant with sharp corners and precise right angles - produces a cleaner, more geometric sparkle than round cuts, and that geometric energy translates naturally to the continuous curve of a hoop. At 1.75 carats total of princess-cut white cubic zirconia set in warm 18K yellow gold over sterling silver, these earrings have genuine sparkle presence while remaining a wearable hoop shape. The warm gold setting amplifies the near-colorless cubic zirconia through contrast, making the stones appear more vivid against the yellow gold than they would in a cool silver setting.
