Calligraphy Jasper Tumbling Rough

Calligraphy Jasper Rough for TumblingRough Calligraphy Jasper for tumbling is available to buy in our Rough Rock Shop in 100 gram packs.

Calligraphy Jasper has a hardness rating of 7 on the MOHS scale.

I put one polished face on a piece of Calligraphy Jasper to give you an idea of how well it polishes. Have a look in the video below. Note this was not done in a rock tumbler but on my diamond polishing machine.
