Vintage Gemstone Necklace-Redish-Blue Gray Beads

Interesting vintage, stone bead necklace. It measures about 17" long. These natural stones are a bit crude, with some having chips on their edges. There are metal spacers that show some corrosion. The darker stones are a blue-green-gray color, and the red is a rusty-red color (not quite as bright red as my main picture). Great boho, hippie style necklace.
