This came quickly and on time, and just as described.  However, I didn't really note how big 13mm is... I just assumed it was a "normal" sized pearl.  13mm is big; much bigger than a pea, almost the size of a marble.  I bought this for a young girl, so I think the larger size actually "works."  However, if it were for an adult female, the size would be too big to look real.

Good gift for younger women.
