Druid stone (fluorescerend Sodaliet). The real name is Syenite, which closely resembles granite. The rock exhibits the same colors, and in terms of grain size and structure, they do not differ from each other. Syenite is a medium- to coarse-grained magmatic intrusive rock that contains little or no quartz. It consists of Potassium Feldspar: Plagioclase. Sodalite belongs to the Feldspar substitutes, which makes it extremely special that Sodalite is found in the Syenite. Yooperlite is the trade name, some also call it Glowing Stone. They are a sodalite-rich syenite, the sodalite in its current form is also responsible for the "glow." We also jokingly call the stone Shamen or Druid Setin, because we have customers who work with it very, very successfully in a shamanistic way... it's precisely the connection with the earth and the mysterious gaze you can peer into, it drives people completely crazy ;)
