Help identifying types of pearls please

[Cmrpro1982]

Hello, I need some help identifying some pearls I have. I’av been buying and selling jewelry for a while, I don’t know to much about pearls to be honest besides the tooth test. I’av bought these with in the last 3 to 5 years because they look decent and the clasp was gold on all of them. I have 3 necklaces and one set of earrings. I numbered them on the pictures 1-4 so it’s easier for us to communicate about the m. All have 14k clasps, but The one labeled number 1 has the best clasp which is 14k gold with a platinum setting and 3 mine cut diamonds and small European cut diamonds around them.thanks for any help I can get, I av been watching video on youtube about pearls but the whole types still confuse me a bit. Thank You again.
