Glass Pendant on 20" Silver Tone Chain Red/Black Dichroic Shimmer VGC

Beautiful vintage 1990s glass pendant Approx 1.25" in diameter Red with black wavy stripes pattern with a black background which gives a shimmery, glittery, dichroic effect - pendant appears dark when looking at it straight on, but quickly brightens and shimmers as you move to the sides (see pics) Comes on a delicate 20" silver tone chain with a lobster clasp (not stamped that I can see) In very good condition all around with no chips or cracks, and no significant signs of wear
