Gemstones

Alabaster, a fine-grained, compact variety of gypsum used to make elegant vases and other decorative items, is quarried in the foothills northwest of Forth Collins and at a quarry south of Carbondale. However, it is not a gemstone because it is so soft (Mohs scale of 2). That is why it is easy to carve with steel tools.
