These were found in an early sealed Daniel Swarovski export box from around 1910. The Swarovski story began in 1895 in Wattens, Austria, when Daniel Swarovski invented a machine for cutting and polishing crystal. His invention not only revolutionized crystal manufacturing; it went on to inspire the worlds of jewelry, fashion, art, design and cinema over the next 120 years.
