Faceted beads are probably some of the more popular and commonly used type of bead. They come in a wide variety of shapes and sizes. There are even different types of faceted beads.
Basically, faceted beads are smooth beads that have facets cut in the surface. They can be cut by hand or a machine that can cut multiple beads at once. Beads that are hand cut, tend to be more exact, whereas machine-cut beads tend to have imperfections and are commonly fire polished to make the bead surface molten and shiny.
Window beads, table-cut beads, and cut beads are all names that reference faceted beads. These beads are smooth beads that have two or more facets cut into the glass.
The smooth side of the bead is considered the window portion of the bead. On the non-window portion of the bead, there will usually be some kind of coating or finish, like gold coating or matte finish.
There are also cathedral beads that are faceted in the middle. The top and bottom of the bead is usually a patterned glass usually with a gold or silver coating.
