Hello, please could anyone help me identify these pearls, I recently bought them off a lovely lady advertised as south sea pearls with a bespoke 14k gold clasp, she told me they was a gift many years ago and cost around £800, I would like to send them off to get appreciated and was wondering what the experts and knowledgeable folk on here think , are they south sea, tahitian or freshwater ( I know you cannot be 100% sure, , but just some guesses ) thank you
