Fun little paintings of geode slices and raw gemstones.  These are originals and there aren't prints or cards of them, so they're completely one of a kind! 
 
These are matted but unframed - they're a standard size so you can buy a frame at an art supply store and pop the art + mat right in. 
 
Also - all of these can be displayed vertically or horizontally (even the 2 with handwriting in them, as the writing can be read either way). 
 
Pen and ink on watercolor paper, with a simple white mat.

Geode - needs a 5x7 frame
