Rose quartz was designated as South Dakota's state mineral on February 11, 1966. Rose quartz is currently mined in South Dakota primarily for use as decorative pieces, in landscaping and interior decorating, as mineral specimens, in tiles, and in lapidary work. Since rose quartz is a semiprecious gemstone, some use in jewelry is also reported.
Quartz, or silicon dioxide (SiO2) is a very abundant mineral, occurring in many colors, such as purple, pink, red, blue, green, yellow, orange, white, gray or can also be colorless. It's present in many different parts of the world and can be mined from a number of different rocks.
