Can you please check if these are real arabian pearls? ... it comes with a story i bought it from a beauty saloon make up artist who bought it from a bar girl in Angeles City Philippines where many foreigners go since time immemorial ....allegedly a very rich arabian guy visited a nightclub in the area where the bar girl worked and the arabian guy really took fondly of her short of falling in love and gifted this pearl necklace to her ... the girl needed money later as the guy just faded away and he bought it ... he kept it for a long time like years until he sold it to me as he needed money. Thanks a lot
