@alexay123 I love eBay and I do get pearls there...but I hate the Chinese sellers of New pearls on eBay...they are so horribly mislabeled or you will get horrible pearls that look nothing like the photo!!! Take the Pearls as One course then go looking at pearls. If you need just a few new pearls...look on Etsy and find sellers with great reviews that post the photo of the pearls you will get. (They may not be great...but they will be okay for the price). You will also be able to ID many of the used or estate pearls on eBay and pick up some akoyas, tahitians, etc. But don't spend much on all of those...once you get a few used you will find what you like and save up for really nice ones.
The big problem with Chinese sellers on eBay is that opening & closing stores are easy...so by the time you get your mislabeled or horrible pearls...they will have closed their shop and getting your money back will be very hard. I wish eBay could stop them...but they just close that store & open a new one under a different IP address.
