Nine carats of sky-blue topaz - the proprietary sky-blue topaz color - across two round studs creates earrings with genuine colored stone presence: at approximately half an inch per ear, these studs are not accent jewelry but statement pieces in stud format. The clean sky-blue of sky-blue topaz, a color without the greenish tones that affect many treated blue topazes, reads as vivid and saturated across the faceted round surface, catching light with the characteristic brilliance of a well-cut transparent colored stone. Rhodium over sterling silver keeps the cool white setting as clean as the blue it frames. A blue stud earring that functions as a daily statement piece and works as a December birthstone celebration.
