I Purchased the Classic WOC with ruthenium hw in iridescent Black caviar from the 18C collection and was thinking it was going to have more of an oil slick to it rather than silver sparkles. Are all the iridescent blacks from 18c this way? So disappointed because I really wanted a small iridescent black piece. Should’ve taken a picture but it’s going back so I packed it up as soon as I took it out.
