I am living currently in Texas but was born in Eastern Europe.
I have always been a seeker. And I had the collector germ in my blood.
First, stamps, but philately was not a real hobby so it didn’t last long.
Then my attention was diverted to other directions, like chemistry.
I graduated university and earned a PhD in chemical engineering five years later.
I started to collect minerals when I was fourteen, but it was on and off. Not a hobby, just curiosity of my seeking side.
Then I collected art, especially works on paper, until quite recently.
A few years ago, collecting minerals, rocks and fossils became a main attraction.
Most of my knowledge came from Dr. James Carter, a retired Professor with the UTD who is a month younger than me. And also from several friends from this Forum.
Now, I decided to upload some pictures of my specimens on this site.

Have a look at My Galleries to find minerals missing from the Public Gallery.
