Seraphinte is a member of the monoclinic crystal system. It’s mineral class is silicates in the Chlorite group, and its coloring is generally a blackish green with flashes and streaks of silver.
It’s ‘proper’ scientific identification would be Clinochlore (a hydrous magnesium iron aluminium silicate), and contrary to what some might say, it is actually found in many places around the world, including the US. The variety shown, sometimes called Serafina, has come from Russia. It has very positive effects for whatever use is decided upon by its user and is exhibiting some of the highest spiritual aspects versus other locales.
