Explanation

Jasper is a hard, semiprecious stone that's usually red. One of your birthstones is jasper if you were born in the month of March. Jasper is a type of quartz that can be brown, yellow, or green, but is most often a mottled, brick red color. When geologists find jasper embedded in cracks of volcanic rocks, it looks dull and drab, but it's beautifully shiny after being polished. Jasper has been used in jewelry and decorative objects for thousands of years. The word jasper means "spotted or speckled stone," from a Greek root.
