These freshwater pearls are bright white with good luster and a thick nacre. There are no holes that show the irritant beneath. Some pearls have almost a silver cast, but they are mostly bright white. Not all the pearls are perfectly round - there are some in each strand that are teardrop shaped - but overall there is good size and shape uniformity with the strand. The pearls are 3 mm thick on average. Each strand is 16 inches long and contains approximately 32 pearls.
