Vintage 1960s Italian Hand-Blown Black & White Swirl Glass Necklace

My Grandmother loved italy, she purchased this piece from Italy in 1964. It has black handblown black swirl beads, white swirl edge pattern and they were hand-twisted. The shape is kinda like a sugar loaf or a spiral, definitely not your basic round beads. There are little silver spacers in between each one to give it some breathing room. It's a classic black and white look that goes with pretty much anything. It's used but still looks great, no major chips or anything like that.
