JasperJasper is from the chalcedony/quartz group. It is an opaque microcrystalline granular variety of quartz that contains up to 20% foreign material. These materials are what determine the color and appearance of the stone. Because of these foreign materials, jasper is rarely uniform in color. It derives its colorful patterns from other minerals present. The gemstone is often named according to its pattern; landscape jaspers are the most popular. it is usually multicolored, striped, mottled and/or spotted. Here are a few of the jaspers that will make great fall necklaces. Brecciated Jasper is an opaque to translucent colored chalcedony whose broken structure resembles that of brecciated marble. The name for jasper originates from the Greek iapsis for pretty colored stone. Picture Jasper is named for the intricate colorations made by clay and iron that can appear to have hidden imagery like “pictures from the past” Ocean Jasper is silicified (transformed into silica) rhyolite flow from the northwest coast of Madagascar.

It even sometimes flaunts the iridescent white circles so intrinsic to sea spray. Poppy Jasper is a
red, pink and black gemstone. It is so
