Because these are nice dark stones, these make a great addition to an aquarium or large fish tank. They would look great in a vase or a large bowl, too - they make great contrast stones. Tourmaline isn't often tumbled, as it can be quite hard to get a nice finish. In some places you may be able to spot that!

What are tumblestones?
Tumblestones are stones that have been put in spinning barrels with an abrasive compound for weeks or months. This slowly rounds off the rough rock and corners – the stones are then cleaned, and placed with a less abrasive grit. This happens several times until the stones are placed into a barrel with a polishing compound for their final polish.
