These came quickly, are very pretty, and have a nicer higher quality setting than a lot of the other similar CZs available on Amazon. They also came with an extra pair of earrings as a gift, which were similarly sized stones of a pink amethyst shade. Don't know if the gift pair is CZs or not, but they are pretty. My wife is happy with both sets of earrings. Can't  beat the price. The stones measure 6 mm.
