Discover the Hidden Feature of the 1/2 Goldback: The Blue Hue Test

If you hold a 1/2 Goldback up to the light, you might notice something surprising—it’s translucent! When you look through it, everything has a blue tint. But this isn’t just a neat trick; it’s actually an authentication feature, rooted in the science of light and gold.

Why Does Gold Look Blue?

The blue hue happens because of the way gold interacts with light. Gold absorbs longer wavelengths of light, like red and orange, while allowing shorter wavelengths, like blue (around 420 nm), to pass through.

When gold is thinned to a fraction of an ounce—like in the 1/2 Goldback—it creates that striking blue tint. This natural property of gold not only produces a cool visual effect but also acts as an easy way to authenticate your Goldback.

How to See the Blue Hue
