Dear all, could I please get your input about drilling natural abalone pearls. Do you do it? Do you prefer to sand/roughen small pearls (say 3-5mm) and glue them only or put them into some kind of cage/bezel setting? I have two small loose undrilled pearls on the way and I am both scared to give them to my local goldsmith to drill but also scared of them falling off my earrings. What do you think? Thanks!
