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 ready on many of the most beloved crystal colours.
The 'Aurora Borealis' finish, not only increases the brilliance of each crystal, this special application also produces colour changes, as a direct corollary of variations, in the ability of light that falls upon it.
The 'Aurora Borealis' coating itself, consists of a metallic desist applied to a crystal outside using water. A very thin metallic particle sheen is adhered to the glass resulting in a critical enhancement to the crystal's wide brilliance and dramatic colour changes.
These chromatic variations are dependent on the underlying 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 through the spectrum from light, roughly imperceptible, blues to the deepest warm hues.The actual illustrated colour changes depend greatly on the individual crystal cut, dimensions and colour choice, as well as ambient light conditions but in general, darker backgrounds, tend to furnish warm 'fire-like' colours, oranges, yellows, gold, reds and ambers. While in contrast, 'light' conditions furnish ethereal blues, greens, lilac, purple and tones with a sense of unbounded 'space'. When applied to each crystal colour singular specific variations can be seen, but in all, the 'Aurora Borealis' desist results in a striking and fantastic display.
