Vintage Glass Multicolored Disc Necklace

Necklace is beautiful, however, pictures do make it look more vibrant than the colors are. Still bright but not quite as bright as photos make appear to be Necklace is in excellent condition, unsure if it is brand new, or worn. Necklace features large flat colored discs separated by smaller beads also varying in color and a twist lock chain for a secure fit. Plastic cord supports the beads which feel like glass, necklace does have some weight to it when lifted. See photos for measurements I don't know much else about this brooch other than it was purchased by my grandma and found prior to her estate sale.
