Uraninite (Pitchblende) – The Primary Ore of Uranium
Discover one of the most historically significant radioactive minerals ever found. Uraninite, often known by the older name pitchblende, is the principal ore of uranium and the source material from which radium and other radioactive elements were first isolated. This remarkable mineral played a pivotal role in the groundbreaking research of Marie and Pierre Curie, helping usher in the modern age of nuclear science.
Typically appearing as black to dark brown masses with a submetallic to greasy luster, uraninite is prized by collectors for its density, geological importance, and naturally occurring radioactivity. Over millions of years, uranium within the specimen slowly decays into a suite of daughter products, creating a fascinating natural record of radioactive transformation.
Whether displayed as a scientific curiosity, historical specimen, or centerpiece of a radioactive mineral collection, uraninite remains one of the most sought-after uranium-bearing minerals in the world.
Highlights:
• Primary ore of uranium
• Historically linked to the discovery of radium
• Dense black mineral with metallic to greasy luster
• Naturally radioactive
• Essential specimen for serious mineral and element collectors
A classic mineral that helped change the course of science.
