Remember this picture from a post yesterday? I usually go back to posts after a while and re-read them and edit typos I catch. I was doing that and getting caught up in this picture. Then I noticed something. Do you see it? Over to the right of the shell is a little Lemurian quartz crystal and it has a colorful triangle on it.
What is that? I thought. This is a clear white crystal.
Do you see it now? Zoom in. I think it is acting like a prism and projecting the colors of the abalone behind/underneath it.
