Agate slice in brass adjustable round stand
PUMI1899-19
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,. Each flood led to a layer of different density, color... That's how a hole becomes such a wonderfull agate. In this case the layers are even more obvious when light comes through this slice (4th picture).
