Gold normally absorbs blue light, which gives it its yellowish hue. Silver metals absorb and emit just about every frequency of visible of light (which means they're actually colorless).
By carving a pattern of rings onto a metal's surface, the properties of its electrons, called the resonant frequency, is altered. By varying the size and depth of these rings, the frequency of light a metal absorbs and reflects is changed. No other properties of the metal are affected.
This is essentially the same technique that scientists are using to create invisibility cloaks, except that instead of trying to make light pass through a material, they just want to redirect how light is reflected and absorbed.

awesome, I want a crimson red ring, that would be really sweet
This is cool!
Invisibility cloaks? What where!?
I want one that can disappear entirely.
this has the potential for some extremely hideous jewelry
Wow, that's pretty awesome. Now if only they could make one that didn't make your bank account disappear.
Color of gold is still the best if you ask me.
im gonna take out all my teeth and put crimson red teeth
It's pretty cool, but I can't see them using it all that much save for minor highlights. Because really, when you buy a gold piece you want people to know it's gold.
isn't the point of having a GOLD band so that you and others can see that it's the colour of GOLD? It would be silly to go "hey, look at my gold ring" and hold up a ring that's bright blue.
I want my gold to remain golden, thanks. But that invisibility cloak thing might have promise.
i think the idea of having a gold band is uhm... it's gold?
I'm going to buy some invisible jewelry fro Xmas.
just like in LoTR
That's pretty awesome! :)
