Made in the Czech Republic, the facets of these fire polished beads are first cut by machine. Then the surface is polished as they are fed through a red-hot oven. For our line of Lumi coated colors, a luster coating is fully applied to the surface of the clear crystal base. This coating creates a brilliant color which changes slightly as the facets catch the light at certain angles. Most of our inventory is temporarily strung. Please note that small imperfections will occur as part of the manufacturing process and size, shape and color may vary slightly from lot to lot.
