This listing is for a pair of glass and gold midi studs with a clear glass base with crushed furnace glass for a unique mottled effect. 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!) Due to high demand these are made to order so the gold pattern may differ slightly from that in the image. 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 24 carat gold leaf as an embellishment.
