3x Large German Red Jasper Tumblestones

We collected these pieces of jasper on the banks of the German river Rhine and tumbled them in our own tumbling machine.
The jasper comes from the Lahn-Dill region in Germany and it is a quartz with iron inclusion. The red colour of the japser comes from these iron inclusions.

-TUMBLED STONES-
These are stones that were tumble polished in a rock tumbler.
The rough stones are put into the tumbler with abrasive grit where they are tumbled for weeks, during this time the sharp edges are rounded off.
During the process, ever finer grits are used and so the stones are slowly getting a smooth and shiny surface.
The final stage of the tumbling process is using a special polishing powder instead of abrasive grit to polish the stones to a mirror finish.

PLEASE NOTE: These are natural stones which we only slightly tumbled so that they retain their natural form.
Due to this, the stones have smaller cracks and pits as can be seen on the pictures.
