Value of Miriam Haskell Necklace?

I purchased this necklace today at a junk shop and positively love it...just paid $5 for it. Got it home and looked for a mark and found out it was a Miriam Haskell piece....I was thrilled.

I was wondering if anyone would know the approximate value and how can I possibly clean it. The "pearls" feel a little dirty. The leaves are metal.
