Original Message:   Red Opal Czech Glass - interesting tonal change
The Czechs evidently produced these beads about 20 years ago. The glass displays a dramatic difference in transmitted versus reflected light - goes from bright ruby to garnet. Worn in sunlight, bright red. In a shaded room, garnet. Thought it was kinda neat.... Copyright 2024 All rights reserved by Bead Collector Network and its users
