Some of us in South Florida met a husband and wife team from Uruguay who have been bringing pearls up to the US for the past few years... and, though we have been able to cherry-pick the inventory, most of the material is in well-worn condition.

I have one yellow example in my collection that's in excellent condition and had only one or two others that were as nice as yours without having any rim nicks/chips.

I paid $10 each for my examples.
