Vintage "Rock Candy" Glass-Like Necklace

Necklace is in link new condition, see photos Chunky Rock Candy Necklace (No not actual Candy) is very unique and features intertwined strains of soft pink and white polished stones (unable to confirm actual material). See photos for measurements, lobster claw clasp for secure closure, necklaces does have a bit of weight to it give the materials used to make it. This chunky statement piece screams unique style and would look awesome either dressed up in the office or down with a piece of jeans and a flowing top. I don't know much else about this Necklace other than it was purchased by my grandma and found prior to her estate sale. Questions? Please ask prior to purchase.
