The pearls' surface and color are not entirely uniform but it is not too obvious considering their size.
6 out of 10 pearls come with residue glue on them, but I simply 'popped' the glue off with my fingernail so it is not really a problem.
The only reason why I took one star off is because my pink pair come in two different shade...

Overall, I think it is 10 dollar well spent!
