Transparent: Light passes through a transparent bead much like it would through a stained glass window. (You can see through it). Transparent beads transmit light and you can see into or through them, even when they are coloured. Transparent beads are more lively or “sparkly” than opaque beads.
Silver lined: A transparent coloured or clear outer layer which allows the silver lining on the inside to glisten through, giving added reflection. Silver-lined beads are made with a transparent or opal glass and have mirror-like reflective lining in their holes. Usually, but not always, the hole is square to enhance the bead’s reflectiveness.
Translucent: Somewhat clear (not as clear as transparent) – light can pass through.
Rainbow: An iridescent coating on the outside of either opaque or transparent beads.
Opaque: Light cannot pass through an opaque bead because opaque beads transmit no light. You cannot see the thread in an opaque bead.
Metallic or Galvanized: A shiny, very reflective coating that gives the bead a look of metal. Metallic or galvanized beads are glass with shiny metal like surface coating that is usually a baked-on product. Test the beads overnight in bleach, acetone or alcohol to check for permanence. Try not to use on bracelets or backs or necklaces where they will receive abrasions or anywhere they may receive a lot of sunlight. Three or four coat of a spray fixative can prevent the surface from wearing off quickly. Bronze, hematite and copper are more permanent because they actually have metallic lustre finish.
Inside Colour: The surface layer is clear while the colour adhered to the inside shows through the clear layer.
Matte: A finish that has dulled or less shiny, perhaps frosty appearance. Light does not reflect off the surface as it does with a highly polished surface. Matte beads have velvety or frosted surface. Matte iridescent beads are both iridescent and matte. These cannot be etched to make simply matted.
Lusted: sequins are transparent, opal or opaque beads with a transparent, uniform, slightly shiny finish that is usually permanent. Finishes may be white, coloured or even gold.
Iris is an iridescent coating on dark opaque beads with multiple hues.
Ceylon: A pearl lustre finish. Sometimes the colour of this bead fades when exposed to strong sunlight.
Aurora Borealis: Named for the northern lights, aurora borealis is a term for crystal stones that have a highly iridescent surface.
