Please help me identify if these are real pearls & what kind

[CassA]

I have a possible pearl necklace in a Nicolette by Valmonds red velvet box & a pearl bracelet I picked up while volunteering at an op shop. I can’t make out the stamp on the necklace clasp & the bracelet doesn’t seem to have one but both items have the gritty feeling on the teeth.
Can anyone please help confirm that these are real & if possible, what type & origin.
Thanks

These are Chinese freshwater pearls. The "14/20" mark on the ball clasp indicates it's 14K gold-filled (1/20th gold by weight; 14K gold plated over base metal.)
