Samarskite-(Y) Mineral | 3.4 grams | South Platte Pegmatite Mining District | Jefferson County, Colorado, USA | SO24

Samarskite is a radioactive rare earth mineral. Samarskite crystallizes in the orthorhombic – dipyramidal class as black to yellowish brown stubby prisms although it is typically found as anhedral masses. Specimens with a high uranium content are typically metamict and appear coated with a yellow brown earthy rind.

Samarskite-(Y) is rich in rare earth elements (REEs), niobium (Nb), and tantalum (Ta)—all of which are valuable in advanced electronics, alloys, and green energy technologies. The mineral can also contain trace amounts of uranium and thorium, which may cause it to be slightly radioactive.

Due to its uranium content, samarskite-(Y) is considered radioactive. It's recommended to wash hands after handling and avoid inhaling dust when breaking or handling the mineral. 

This specimen is in very good condition and displays very well.  Make this a special specimen in your collection.
