Opal belemnites are very unique pieces for any collection. These are squid that have been opalized. Opalized fossil squid are rare and precious.

The different colors you see in opal is due to millions of tiny hydrated silica spheres of different sizes. Silica spheres refract the light and cause the magnificent spectral colors you see in the opal. Interestingly enough, the spheres have to be uniform and just the right size in order to create enough color for our eyes to actually see it.
