If you're finding for a piece of crystal jewellery, you will no doubt have seen many references to 'Aurora Borealis', 'Ab' etc. Many habitancy assume 'Aurora Borealis to be a colour in it's own right. In fact, as a extra 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 extra application also produces colour changes, as a direct succeed of variations, in the potential of light that falls upon it.
The 'Aurora Borealis' coating itself, consists of a metallic end applied to a crystal face using water. A very thin metallic particle sheen is adhered to the glass resulting in a important enhancement to the crystal's broad brilliance and dramatic colour changes.
These chromatic variations are dependent on the basic 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, approximately imperceptible, blues to the deepest warm hues.The actual visible 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 yield warm 'fire-like' colours, oranges, yellows, gold, reds and ambers. While in contrast, 'light' conditions yield ethereal blues, greens, lilac, purple and tones with a sense of unbounded 'space'. When applied to each crystal colour particular exact variations can be seen, but in all, the 'Aurora Borealis' end results in a stunning and brilliant display.
