Interesting Nuummite tumblestones, measuring 20-30MM approximately.
Nuummite is a fairly rare stone, and is not one of the more common ones typically sold as tumblestones.
It is only found in Greenland, and is one of the oldest rocks on Earth, formed around 3 billion years ago.
They make a nice display item in a bowl, or a vase, and are good contrast stones against something lighter. These stones have an interesting surface sparkle, due to crystal inclusions.
As we do not have a steady supply of these stones, we currently sell them singly.
