Red Jasper is an ancient and sacred stone that has held meaning throughout dozens of cultures since the beginning of human existence.
This is due to the combination of red Jasper relative popularity (meaning that it exists in various locations and was readily available to the people in them) and its attractive appearance.
The colors that Jasper appears in include blue, red, green, yellow, black, or even the distinctive green-and-red speckled variety known as Bloodstone.
