Packaging unit with 0.5 kg; this is about 47 - 53 Tumbled Stone Tourmaline Quartz in size M (medium).
The size of the L Tumbled Stones is about 2.0 - 2.5cm.
As in these Tumbled Stones the black Tourmaline (black) combines with the light quartz, so the Tourmaline Quartz stands in stone healing for the connection of (apparent) opposites and the dissolution of polarities.
