Mimiruff, I have a modest collection of freshwater, Akoya, and South Sea pearls, and with the exception of six pieces, they were all bought in the Philippines.
For the most part, the local vendors were all upfront and honest about the types and sources of their inventory. Of course, I am also a local and by now, a familiar face, so they are transparent with me. But you can also ask jmd, who lives in the US, about her experience with the Philippine pearl market.
In my experience, the ones that are consistently misrepresented are sold on eBay; almost all, by China-based merchants. The warnings on this forum are, sadly, justified.
But you have the right attitude towards pearls. Pearls are like children; we all want ours to be the best and most valuable. Thankfully, each pearl is beautiful in its own way. I still love and wear my first chunky, egg-shaped freshwater pearls, even though I now own better pieces. Likewise, I can tell that you will take pleasure in yours. Enjoy!
