Squash Blossom Appraisal

Hi All,

I am selling jewelry for a friend and she has a Squash Blossom necklace. I took it to a jeweler and he said it could possibly be a Sleeping Beauty Squash Blossom necklace.

Here is a link to my Poshmark page to see the item.

Please help me to determine if this is real and if so, what price range I should be in.

Thank you,
