Hattie Carnegie Necklace

Last summer i had purchased at a tag sale in Plattsburgh, NY (I believe for 75 cents) this Hattie Carnegie Necklace. I havent been able to find any information on this particular necklace, all the jewelry of hers ive seen online arnt even close to this necklace. (and honestly, all I know about the designer is what i read on Wikipedia http://en.wikipedia.org/wiki/Hattie_Carnegie) The Necklace is 29 inches long with 26 clear teardrop beads (not sure what the material is, but boy do they sparkle, they start smaller by the clasp and get larger in the middle and than go smaller again) and those 26 beads alternate with 25 globe shaped beads with stones that sparkle like diamonds but arnt. (they start small like the other beads and get larger and than smaller agian.) I want to know when this necklace dates back to and what its worth.

@ still looking for information on this necklace. Updated photos@
