My biggest passion is geology,and in particular, mineralogy. I have a collection of several stones that I have been collecting since I was ten years old. i love geology because it teaches me more about the Earth and its natural processes.
Let me share some highlights of my collection if I may. Keep in mind that I did not collect a lot of these out in the field, but rather I purchased most of them online.
Natural blue topaz. 5,220 carats (2.3 lbs/1,044 grams). Canta Galo Mine in Nova Era, Minas Gerais, Brazil.
Iridium (Ir) ingot. 5 grams. Smelted in the US from iridium metal powders refined from platinum ores in South Africa.
Ruby (corundum). 2,608 carats (1.14 lbs/521.6 grams). Karnataka, Mysore, India.
Trilobite fossil. Devonian-age Columbus Limestone. Delaware County, Ohio, USA. (collected by me on a field trip)
