What is the difference between a colour and an effect?
A coloured crystal is completely permeated with a base colour from the time of its creation, whereas the creation of crystal effects begins with a pure sparkling crystal, which is normally the basis from which to start. The creative effect is then achieved through a special finishing/coating process, which applies the effect to the surface or back of the crystal, depending upon the desired outcome.
What is an effect?
Swarovski® crystals offer both surface and translucent effects. Each surface effect has a vacuum coating on the obverse side of the crystal. Alternately, a vacuum coating on the reverse side of the crystal generates a translucent effect, which is intensified as it shines through the transparent crystal.
AB (Aurora Borealis) crystals are coated to give an iridescent rainbow effect to the faceted faces of the crystal. AB clear crystals are clear and their iridescent coating gives off silver, yellow, pink and purple tones. There is a select range of AB crystals with a coating which transforms the colour of the crystal completely from its base colour.
