Very old turquoise glass & crystal clip earrings vintage

These beautiful earrings are very old and feature small opaque turquoise glass beads and clear quartz crystal beads. You can tell from the wear on the facets of the crystal beads that these are very old; the beads are Czech. The clear ones flash rainbows in the sun. Please look closely at the photos as they are part of the description. ** This item is part of an estate sale haul from an elderly lady who had her own jewelry, and some jewelry from her mother. It's all vintage/antique, mainly costume jewelry, high quality and stored safely over the years.
