Vintage Preciosa Czech Watermelon Vitrail Glass Earrings

Vintage Preciosa Czech Watermelon Vitrail Glass Balls earrings. These are beautiful - and hard to photograph! They change color in different light. The back is silver on the outside. The color you see depends on the angle from which you're looking. The balls measure 12mm at their widest, and the flat back is smaller 7.5mm but it gets wider with the roundness of the ball. Made in the Czech Republic.
