We sell high quality specimens of Pitchblende, Uraninite, Autunite, Schoepite, Curite, Kasolite, Becquerelite, Cuprosklodowskite, Torbernite and other radioactive minerals containing Uranium or Thorium from many of the world’s most famous mines. We also sell rare collectables from WWII and the early era of the nuclear power industry. We have many satisfied repeat customers as well as those who are new to collecting. We’re owned by Pro Partners & Associates, which has been in business for over 15 years as a provider of unique items for people with unique interests.
Believed to have originated in supernova explosions, Uranium is the heaviest natural element on earth, and it continually decays over time with a half-life of 4.5 billion years. It was discovered by Klaproth in 1789 in the black mineral Pitchblende and in 1896 Becquerel demonstrated that Uranium was radioactive.
In 1898 Marie Curie discovered a new element in Pitchblende that was a part of the Uranium decay chain. She named the new element Radium and it is incredibly over 2 million times more radioactive than Uranium itself.
Fission was discovered in 1938 by Otto Hahn and explained theoretically in 1939 by Lise Meitner. U235, the raw material for fission, was in very short supply at the time as only 0.7% of natural Uranium is composed of U-235 (99% is U-238, and a trace amount is U-234).
Shinkolobwe mine in the Katanga province of The Congo was identified as a source of uranium by the English geologist Robert Sharp. Shinkolobwe ore contained Uranium at levels as high as 80 percent, the purest concentration found anywhere in the world. The 231 gram sample of Uraninite with streaks of Gummite shown below is from Shinkolobwe. Attesting to its high quality, It measures 200 mR/hr and 580,000 CPM on a Ludlum Model 3 counter with a 44-9 probe.
