Packaging unit of 0.5 kg; this is about 30 - 40 Tumbled Stone Tourmaline Quartz in size L (large).
The size of the L Tumbled Stones is about 2.5 - 3cm.
As in these Tumbled Stones the black Tourmaline (black) connects with the light quartz, so the Tourmaline Quartz stands in stone healing for the connection of (apparent) opposites and the dissolution of polarities.
