INCREDIBLE 18", 10mm faceted blue sapphire beads and gold tone beaded necklace!

Found this incredible piece at an estate sale long ago, and I've been holding onto it because I wasn't sure what stones they were initially. So, this is a heavy piece! There are approx. 49 (I counted a couple times) 10mm blue faceted sapphire beads. There are some gold toned beads throughout and in between each sapphire. 18" long and with a 2" extender.
