Hotaru glass, with its deep blue color reminiscent of the Okinawan sea, is a glass bead with a hole, made using a shaping technique called burner work, similar to tonbo-dama (glass beads). Artisans melt colored glass one by one onto an iron core, and then layer silver foil onto the molten glass, like syrup, using a special technique to create beautiful colors. There are no clear records of when Hotaru glass, a type of tonbo-dama that originated outside of Okinawa, became popular as a souvenir in Okinawa. However, it gained attention in the late 1980s as a replacement for rare coral products, and it is said that its deep sea-like colors captured the hearts of tourists. ・The attachment part is an earring hook (gold color, brass). ※ You can also get silver-colored (brass) hardware for no additional charge.
