Pistachio jasper, an aggregate of microgranular quartz and/or chalcedony and other mineral phases, is an opaque, impure variety of silica. It can be highly polished and is used for vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. Along with heliotrope (bloodstone), jasper (green with red spots) is one of the traditional birthstones for March. Jaspilite 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).

Pistachio jasper is prized for its subtle green hues, often ranging from soft sage tones to brighter pistachio shades. Its unique coloration can include delicate marbling or swirling patterns, giving each specimen an individual character. Many collectors admire pistachio jasper for its gentle, inviting appearance, which makes it an excellent stone to display in various decorative settings. Whether used for fine jewelry, miniature sculptures, or ornamental pieces, pistachio jasper continues to captivate with its natural elegance.

Because pistachio jasper is relatively hard and durable, artisans throughout history have carved intricate designs into it to create beautiful decorative objects. Contemporary jewelers often incorporate polished pistachio jasper cabochons into necklaces, bracelets, and rings, showcasing the stone’s subtle color palette. Beyond aesthetics, some enthusiasts appreciate this form of jasper for its ability to take a high polish, resulting in a smooth, glossy finish that highlights the stone’s intrinsic beauty.

Similar to other jasper varieties, pistachio jasper forms through the consolidation of fine-grained quartz and other minerals under sedimentary conditions. Over time, these minerals bond and harden, creating the distinctive patterns visible in the stone. With proper care, pistachio jasper objects and jewelry can retain their luster and intricate designs for generations.

History

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, Azerbaijani, 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. The jasper of antiquity was in many cases distinctly green, for it is often compared to the 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 yushphah 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.
