I'm finally back in Alanya, Turkey and having a great time.
While walking down the street, I coincidentely saw a store with some crystals in the window, so I had to go and look what it was. I was surpriced to see that the store was mostly a mineral store, and had a long and interessting talk with the owner. I ended up buying several pieces, and probably I will go back for more. The picture below is a Dentrical Agate with Opal, from Eskişehir, located in the Central Anatolia north in Turkey. Both the white agate and the yellow glass-like opal got black dentric inclusions, formed as small trees.
Dendritic agate is a translucent, colorless to whitish-gray variety of chalcedony quartz, easily distinguished by its distinct tree- or fern-like markings known as 'dendrites', which are most often brown to black in color The bands of this agate sometimes are filled with opals and for this reason sometimes this agate is called dendiritic opal.
I find this piece totally amazing, because of the combination, and because I think the pattern looks like a man with his boots, hands, head... call me crazy, but it is stuff that this I love. No one creates more beautiful art then the nature itself. So this one is my first piece of Minerals in my turkish home, and not the last :)
