Complaining to the MyPacificPearls sales staff is pointless as they are probably just squeezing what they can out of Groupon before shutting down the site to restart under another name.
The target of your wrath should be Groupon. Groupon clearly didn't bother to research the product. They are more than aware by now that there is a major problem with MyPacificPearls, but they continue to run the deals.
I made the mistake of ordering these back when there wasn't much discussion on the web. I wasn't expecting the strand to be worth hundreds, but thought $79 wasn't bad for pearls that size with a gold clasp.
MyPacificPearls advertised the pearls as 9mm to 10mm. The strand I received contained pearls from 7mm to 9mm, mostly smaller pearls. The "peach, lavender and white" strand turned out to be goldish, off-white and white. As noted by others, the clasp wasn't gold, but gold-filled.
Here's their response to a request for an RMA:
We are disappointed to hear that your purchase did not meet your
expectations. Do bear in mind that it is normal for genuine pearls to have
natural surface imperfections due to how each pearl forms within an oyster
or mussel. This does not take away from the fact that these are beautiful,
authentic pearls with an estimated retail price of $1550.
"Estimated retail price" is always inflated, but $1,550 is delusional. A similar strand is available on Amazon for under $30.
On the upside, this deal made me realize that the Groupon model isn't viable - and saved me from a costly investment error.
