Hello,
since it cannot be possible to get that prices for that pearls as described, how would you trust clasp to be true 14 kt ?
Just "ask seller a question" about "TRUE or only "looking like colors" or maybe " shell pearls" for his Tahitian, Akoya and South Seas claimed original true ones and judge with the answer.
Here is my opinion :
