Main Difference
The main difference between Jade and Jasper is that the Jade is a ornamental stone and Jasper is a chalcedony variety colored by iron oxide
Jade
Jade refers to an ornamental mineral, mostly known for its green varieties. It can refer to either of two different minerals: nephrite, a silicate of calcium and magnesium, or jadeite, a silicate of sodium and aluminium.
Jade is featured prominently in ancient Asian art, as well as having an important place in many other cultures.
Jasper
Jasper, an aggregate of microgranular quartz and/or chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. The mineral aggregate breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. A green variety with red spots, known as heliotrope (bloodstone), is one of the traditional birthstones for March. Jaspilite is a banded iron formation rock that often has distinctive bands of jasper.
