A worry stone, also called a thumb stone, is a small indented oval-shaped polished mineral or gemstone. It's basically an ancient fidget spinner: it feels good to hold and run your thumb across the smooth surface and it can be soothing. This is great one if you like squirreling away stones in your pockets!

A good worry stone will help you forget how dry your hands look in all the pictures, oh god don't look at that. It will be relatively lightweight and thin to fit between the fingers; larger "flat egg" shaped stones can be called worry stones but are more typically called palm stones. In comparison cheaply made worry stones will look clunky, thick, and have a visible line where the indentation begins. That edge can feel rough compared to a normal worry stone which is very smooth with no edges.

This Picasso jasper is extra satisfying as a worry stone. It feels slick and cool, and has good heft despite being quite thin. You may notice you can feel the stone's pattern a bit due to light changes in surface height between materials.

Picasso jasper is in fact not a true jasper, but a variety of limestone. It gets its name from the bold blocks of black and gray reminiscent of the artist's style. Pieces may also have veining or dendritic patterning.

One for you, one for your pods! I find this the perfect size for an isopod feeding dish to use in my nicer terrariums. The slight indentation helps keep food in the center. I thought they might be too smooth for mancae to climb but that hasn't been an issue! Even though it feels smooth to us, the aggregate crystal structure is quite textured at their scale.
