A little history: "Jasper is an opaque chalcedony that comes in a wide variety of colors. The term "jasper" itself comes from the Greek work iaspi meaning spotted stone. Unlike most jasper which is a heavily banded variety of chalcedony, brick red jasper is almost one pure color. Jasper is a gemstone that has been used all over the world and often revered as sacred. According to Norse legend, the magic sword of Siegfried the dragon slayer was inlaid with this gemstone. Egyptians believed the stone to be associated with Isis and was carved into amulets for the dead. There is also speculation it was actually red jasper (not ruby) that adorned the sacred breastplate of Aaron.
