Enjoy beautiful crystal colour with our great range of agate slices. These agate slices come in a choice of colours that show off the banded structure of the crystal. These slices are thin enough to let light shine through the agate, which makes the colour glow beautifully - place them in front of a window for maximum effect. Agate slices are a striking and inexpensive way to expand your crystal collection and make great gifts. We also have thicker agate cut base slices and agate geodes.
