Yes, Pearlescence, i've just have official papers for my new trade, before pre registration for HK Show,
i was thinking about my trade since some years (notebooks full of pearls jewelry designs, learning threading pearls, thank you Henrietta' book, PG members and you tube), and seriously since last year, GIA Pearls graduated (internet from September to December 2015, computer in front of me and english dictionary on my left ! , and lab class in London on March 2016, very proud with my GIA Alumni Association Members card !!)
for the whosaler offices, good advices, i'm trying to contact some of them for an appointement before the show, if it is not possible, tourism is a good alternative, too ! After all i hope for more shows in the future !
