Japanese Glass 6/0 Seed Beads
(Miyuki)

Opaque beads are a solid color.  

Silver-Lined beads have a shiny silver color-lining of a transparent bead.   The bead may be crystal, or any other transparent color.

Color Lined beads have a color lining of an transparent bead.   The colors vary, including special color effects.   The transparent bead may be crystal, or any other transparent color.

Matte (or Frosted) beads have an etched look to them.  

Semi-matte beads have a mixed glossy/matte finish to them.   They are a little brighter than regular matte finish beads.

Metallic and Metallic Iris beads have a metallized finish.   Sometimes, this finish rubs off.   Use a clear fixative like Krylon spray.   

An Iris finish is a multicolor effect, which creates a rainbow type effect all around each bead, but also causes a range of color hues and tones within any mix.

A luster finishes creates an irridescent shine around the bead.

Galvanized beads have a coated finished applied to the glass through a galvanization process.  This finish does come off, so we suggest you use a clear fixative, like Krylon spray.

Ceylon beads have a pearlized finish.   Sometimes the pearlized finish has been dyed to attain a particular color.  

Alabaster S/L Dyed beads started with a silver-lined translucent bead, and then dye the bead to a certain color.    As with all dyed beads, we suggest you use a clear fixative, like Krylon spray.

Hex-Cut or 2-cut beads have 6 faceted sides to them.
