Fire-chromed glass Skull beads, a unique and luxurious material, are used in these stainless steel (black anodized) hoop clasp pierced earrings. These earrings, adorned with faceted and smooth fire-chromed glass beads, dangle 1 1/2 inches (4 cm) from the earrings' hole. Key points about fire-chromed glass beads: "Fire polished": This meticulous technique involves heating the glass beads in a kiln to melt the edges slightly, creating a smooth, polished look that reflects the dedication and care put into each piece. "Chrome finish": The beads are then coated with a layer of chrome plating, giving them a metallic sheen. Origin: These beads, a testament to the artistry of the Czech Republic's glass bead-making tradition, are often manufactured in this region, which has a long history of skilled craftsmanship.
