This listing is for a pair of glass and palladium midi studs with a clear glass base with crushed furnace glass for a unique mottled effect. They are a limited edition of 10 pairs so I can gauge what you guys think of palladium on the larger studs! I have handmade them from sculpted hot glass, 24 carat gold and surgical steel backs. The glass has been shaped freehand, so the earrings are not identical, but still a matching pair! (I think it gives them character!) Surgical Steel is hypo-allergenic. The steel backs are fused into the glass while it is still hot, so no glue. They are made with a lovely shiny glass, and precious metal Palladium for an accent.
