These 8mm glass cathedral beads from the Czech Republic are the perfect bead if you love to add extra sparkle to your jewellery making designs. The North Bohemian region, with its centuries-old glass-making traditions, has become the cradle of machine cutting & polishing. Cathedral glass beads are named after the stained glass windows of churches and were first manufactured in the 1950’s. They are pressed and cut, in a way which gives them high light refraction and colour saturation.
