If you put a piece of rough Rose Quartz like the one described above into a Rock Tumbler it will be ground and polished into a shiny gem.
The process is similar to how nature creates the rounded pebbles you see on a river bank or beach. Inside a rotating barrel rough rocks tumble over each other like in a fast-flowing river, and their sharp edges are gradually worn away. A silicon carbide grid accelerates the process. You start initially with a coarse grid, move to finer ones, and finally polish with titanium oxide – which is also used in your toothpaste. Each step can take up to a week. The end results are shiny semi-precious gems which you can mount and wear as jewelry.
