Well, the etsy seller you mentioned is in China also, so there is still the issue of returns and shipping.
You might take a look at IntegrityPearl.com. When you say quality, do you mean AAA rounds? Doug is a member here, but hasn't posted lately. I think he specifies which are the top graded pearls.
You might also contact Jeremy Shepherd at Pearl Paradise, as he sometimes makes special buys/offerings to the beaders here on Pearl-Guide, and request to be on the special mailing list. (That only happens only about once or twice per year.)
The other thing I was going to say--some sellers use generic photos, others take photos of the actual item, so do take note of that, as it can account for differences in what you receive.
