I picked it up because I was intrigued by its two-tone pinks and grays and its banded pattern. I was also taken by the shattered crystal look under its smooth surface. I laid the rock in the sunlight and turned it different ways to get the sketches in this matrix.
Originally, I was planning to paint a dry brush scumble over the wash, but I got fascinated by the way the watercolor paint was doing its own job on the pebble's texture, so I left it alone. I will do the dry brush scumbling another time.
It is obvious to me that I have not exhausted the possibilities in this rock.
