I love pearls. I have 5 stands, all natural or fresh water. This strand claims to be 8-8.5, which is hard for me to believe, as they appear very small. My other 8 mm gray strand pearls look significantly larger. I'd say this one is about 6-6.5 mm. Giving it 4 stars for quality of the pearls. But the size of the pearls seems to be off. Can't recommend the product, honestly. I got it as a gift, but I wouldn't buy it myself.
