Iris Agate

 

BE SURE TO CHECK OUT THE VIDEO FOR THIS SLAB!

Iris Agate is a highly prized and very unique type of Agate.

The stone consists (partly to entirely) of what is known as a diffraction grating. When light passes through the diffraction grating the result is very much like that of a prism, although technically different.

The diffraction grating will often show very thin (or wider) distinct lines of color, and these colors will change as one moves the stone around in front of a bright light source. The key when looking at a piece of Iris Agate is to not hold the stone directly in front of the light source, but slightly off to the side or most often below but still in front of the light.

This approach is clearly seen in the video that we have included along with our regular still photos.

Iris Agate is a real challenge to photograph, and we are really excited that we are now able (for the first time) to include videos in our shopping cart program.
