These olivine and white core Czech glass roundel beads can be used as spacers to give a subtle touch to a design and can be strung together for a beautifully textured effect. The combination of the olivine and white colors with the precise facets makes these beads unique treasures that you will definitely fall in love with. Glass making in the Czech Republic is an age old industry and these beads are still made in small quantities by hand. We work with the finest vendors and have the most consistent, beautiful glass available. Due to the way the glass is made, there may be slight color variation from one batch to the next.
