If you're finding for a piece of crystal jewellery, you will no doubt have seen many references to 'Aurora Borealis', 'Ab' etc. Many citizen assume 'Aurora Borealis to be a colour in it's own right. In fact, as a special coating finish, 'Aurora Borealis' is available on many of the most favorite crystal colours.
The 'Aurora Borealis' finish, not only increases the brilliance of each crystal, this special application also produces colour changes, as a direct follow of variations, in the capability of light that falls upon it.
The 'Aurora Borealis' coating itself, consists of a metallic terminate applied to a crystal covering using water. A very thin metallic particle sheen is adhered to the glass resulting in a critical enhancement to the crystal's comprehensive brilliance and dramatic colour changes.
These chromatic variations are dependent on the basal crystal colour and their intensity is affected by background light conditions. Spectral effects similar to those created when sunlight falls on oily water can also be seen.
The colour variations range straight through the spectrum from light, almost imperceptible, blues to the deepest warm hues.The actual graphic colour changes depend greatly on the personel crystal cut, dimensions and colour choice, as well as ambient light conditions but in general, darker backgrounds, tend to produce warm 'fire-like' colours, oranges, yellows, gold, reds and ambers. While in contrast, 'light' conditions produce ethereal blues, greens, lilac, purple and tones with a sense of unbounded 'space'. When applied to each crystal colour singular exact variations can be seen, but in all, the 'Aurora Borealis' terminate results in a striking and brilliant display.
