Hello again,
So, the pearls are very round, approx 68 smaller pearls, approx 6.5mm, so would likely be cultured akoya pearls.
Silk is stretched, so would be good to have restrung before wearing.
Solid gold 14k fish hook style clasp is also indication of quality.
Do the pearls feel slightly gritty when you gently rub two together? If yes, that would support my feeling that these are cultured pearls, as opposed to imitation pearls. The hesitation I have is that they appear very white in color.
A lovely inherited piece of jewelry. I hope you will wear and enjoy your pearls. You might want to read the section on pearl care. You will want to avoid chemicals such as perfume and hairspray.
