Imperial topaz - the orange-to-golden-orange variety of topaz that is among the most valuable topaz types, distinct from the more common blue or colorless varieties - in hoop earrings creates a piece where the warm orange-gold color of the stone and the warm gold of the 18K yellow gold over sterling silver setting create a harmonious all-warm color composition. Each round imperial topaz catches the gold's warmth and deepens it with the stone's own natural orange intensity. At 0.66 carats of genuine imperial topaz, these hoop earrings have real colored gemstone credentials at a price that the warm gold construction makes accessible.
