Tweetie,
Bacca is right. We are not out to discourage you. Definitely take them in & see what they say.
Maybe try another venue E-bay or Etsy, Craig's list or the like? Consignment shop has been listed & they do certainly take "their cut".
Why Not re-gift them or save for a family heirloom. Do you have any young ladies that may appreciate pearls say for a sweet 16 party or graduation?
What about Donating them to a local fund raiser for say Policeman/Fireman's ball, or animal shelter.
Good luck!
Cheers
