Agate slice on brass base
PUMI1970-1
Before becoming a slice of Agate on our console, it was a round pebble from Brazil in a basalt matrix that has been sliced and polished. And before a pebble, it was a bubble of air in a cooling lava of a volcano. Lava became basalt, a porous stone and the chamber has been filled consecutively over millions of years, by water containing dissolved minerals, like Manganese oxide that gave that black color to the external layers. In this case, Manganese even created strong black dots. Natural and remarkable. photos 5 and 9 shows the difference of color when light comes through it.
