The pink necklace is tissue-nucleated (no bead inside) naturally colored cultured freshwater pearls from China.
The bracelet pearls look just a little egg shaped/off round in the photo; do they look that way in person? If so I'd say they are also freshwater pearls. If 100% round, possibly akoyas. However, the way the clasp is attached is not high end-- no gimp. I lean toward freshwater pearls.
With pearls, grades are assigned by each vendor and are not standardized across the industry. If this helps, I'd say the bracelet pearls are nice but not amazing quality. These days the Chinese produce some very high quality pearls and neither of these pieces is anywhere near the top of the range.
Just for information, pre-owned pearls do not tend to hold their value on resale unless they are historic pearls or a highly recognizable/desirable brand like Mikimoto. If trying to price them, I suggest you search eBay completed listings to see what similar items actually sold for.
I don't recognize either mark; it could be that of the maker of the clasp rather than the maker of the pearls.
