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. Jasper 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. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper.
The name means “spotted or speckled stone,“ and is derived via Old French jaspre (variant of Anglo-Norman jaspe) and Latin iaspidem (nom. iaspis) from Greek ἴασπις iaspis (feminine noun), from an Afroasiatic language (cf. Hebrew ישפה yashpeh, Akkadian yashupu). This Semitic etymology is believed to be unrelated to that of the English given name Jasper (of Persian origin).
Green jasper was used to make bow drills in Mehrgarh between 4th and 5th millennium BC. Jasper is known to have been a favorite gem in the ancient world; its name can be traced back in Arabic, Persian, Hebrew, Assyrian, Greek and Latin. On Minoan Crete, jasper was carved to produce seals circa 1800 BC, as evidenced by archaeological recoveries at the palace of Knossos.
Although the term jasper is now restricted to opaque quartz, the ancient iaspis was a stone of considerable translucency including nephrite.[2] The jasper of antiquity was in many cases distinctly green, for it is often compared to emerald and other green objects. Jasper is referred to in the Nibelungenlied as being clear and green. The jasper of the ancients probably included stones which would now be classed as chalcedony, and the emerald-like jasper may have been akin to the modern chrysoprase. The Hebrew word may have designated a green jasper. Flinders Petrie suggested that the odem, the first stone on the High Priest’s breastplate, was a red jasper, whilst tarshish, the tenth stone, may have been a yellow jasper.
Jasper is an opaque rock of virtually any color stemming from the mineral content of the original sediments or ash. Patterns arise during the consolidation process forming flow and depositional patterns in the original silica rich sediment or volcanic ash. Hydrothermal circulation is generally thought to be required in the formation of jasper.[citation needed]
Jasper can be modified by the diffusion of minerals along discontinuities providing the appearance of vegetative growth, i.e., dendritic. The original materials are often fractured and/or distorted, after deposition, into diverse patterns, which are later filled in with other colorful minerals. Weathering, with time, will create intensely colored superficial rinds.
The classification and naming of jasper varieties presents a attributed to various well-defined materials includes the geographic locality where it is found, sometimes quite restricted such as “Bruneau“ (a canyon) and “Lahontan“ (a lake), rivers and even individual mountains; many are fanciful, such as “forest fire“ or “rainbow“, while others are descriptive, such as “autumn“ or “porcelain“. A few are designated by the place of origin such as a brown Egyptian or red African.
