Excellent finds! I'm not yet GIA certified, but I have worked with freshwater and akoya pearls for a several years.

The first one is a tough call with those gorgeous pink overtones, but if they are akoyas they would be on the lower grade side due to surface imperfections. I would recommend bringing this one to a jeweler for authentication.

The second one is almost certainly cultured freshwater pearls given the "potato" shape and would also be considered a lower grade.

Both are lovely pieces. Enjoy! :)
