Macro Monday

Here is a quick reminder behind "Macro Monday" posts. "Macro" in photography refers to pictures of subjects that are tiny. You bring the very small up to the "macro" level. (When possible, I'll also try to make a puzzle out of it.) 


So, having explained that, can you guess the subject of the pic above? 


The next pic gives you another chance.

It is a large specimen of the violet variety of quartz known as amethyst!
