Vintage Sterling Blue Stone Pendant Bead Ball Sterling Chain Necklace

Vintage Sterling Blue Stone Pendant Bead Ball Sterling Chain Necklace. Large bale that could be put on a much larger necklace. Pendant measures 1.5" (including bale) by .75" wide. Pre-owned, this pendant necklace is in great vintage condition. Pretty blue in the stone. I don't know my stones well but under a loupe there is some glittery aspects to the stone.
