I have a frank heirloom doll, and want it valued?

Does anyone have any idea how much my frank heirloom doll would be? I have Cinderella. She's made of porcelain, and costumed in satin, organza and film lam�. She also has hand made spun-glass slippers, a 22 carat gold plated necklace with several faux pearls. She also has a tiara plated with 22 carat gold and three pearls, and also a half point diamond. It also has the original box and papers, and is in pristine condition. Thank you.
