Mystery Jewel: Vintage Blue Glass Cross Pendant

I found this pendant at the Value Village on Friday. It was so bright and shiny that I picked it up immediately. Then I spent a lot of time hemming and hawing about buying it. Its a solid, heavy and well made piece and my instinct suggests that it dates from 1930 to 1940, but I’m not 100% certain. Do you know how old it is and maybe even who made it? Still, at $9, not knowing made it feel like a shaky kind of risky purchase. I’m also uncomfortable wearing religious iconography. But in the end it’s sparkle won the day and now it belongs to me!
