Assorted gemstone donuts or pi stones are great to use to support your favorite spheres! I have them available in assorted sizes and gemstones in the drop-down box below. These are finely polished and jewelry grade stones if you interested in having one wire wrapped to wear as a pendant.
These are a fabulous alternative to plastic, glass or wood sphere stands :)
It's always trial and error finding the right size for your sphere but I actually placed a 50mm sphere on all three sizes and they did not roll so you can just decide based on whatever stone or size calls to you.
The measurements are approximate and each stone is different as these are all unique and natural stones.
