At 8.35ctw with a diamond equivalent weight of 5.06ctw, this this collection's stud earring in 18K yellow gold over sterling silver is a serious statement piece in a compact format. At 0.42" square, these are large round studs that hold their own at a distance and reward close inspection - the diamond equivalent weight means the CZ is performing at a level that creates genuine optical brilliance rather than costume sparkle. Push back closures. The large-scale round stud in warm gold is the kind of earring that works for a woman who wants her jewelry to make its presence known without requiring a necklace, multiple rings, or other accompaniment. One pair of 5ctw-equivalent gold studs is its own complete jewelry look. The warm 18K gold over sterling silver gold finish amplifies the stone's color performance in a way that white metal cannot - the yellow background creates the warm, rich context that makes CZ look its best. For self-purchase or gifting, this is a statement stud that delivers its value proposition clearly at first glance.
