Thank you for submitting your items for appraisal. This appears to be a 1960s rhinestone necklace and bracelet set, not signed. There are no characteristics which would indicate the authorship of a specific designer. It is a lovely set of pink colour, but I would not dare to attribute it to Haskell. If offered over a longer period of time online or in a shop specializing in costume jewelry I would see price range as stated.
