I “paint” each mineral on my iPad using Procreate. I started with the letters A-Z. Each mineral is created to visually represent the mineral itself and the first letter of the mineral. The second set consists of numbers 0-9. These were chosen in relation to hardness on the Mohs scale of Mineral Hardness and each is formed to shape the number. You can shop prints at 36minerals.com
Below you can see photos of the prints and printed coffee mugs
