Although not really wood, and not even what is called 'Wood Jasper', in small sizes this particular Jasper can many times pass for pieces of wood. It was well liked and used often along with Petrified Wood, since both were readily available all over western America, and even more widespread today. .
In an attempt to keep prices a bit lower, this design incorporates turquoise colored Howlite free form nuggets and chips along with spikes of Picture Jasper. A lobster clasp with an extender completes the necklace. French hook earrings of Picture Jasper rounds and turquoise colored Howlite chips make up the matching earrings to complete the set.

Picture Jasper - Jasper, a form of chalcedony. It is an opaque impure variety of silica, usually red, yellow, brown or green in color. Blue is rare. This mineral breaks with a smooth surface, and is used for ornamentation or as a gemstone. It can be highly polished and is used for vases, seals and in jewelry. Picture Jaspers, just one of many varieties, exhibit combinations of patterns (such as banding from flow or depositional patterns (from water or wind), dendritic or color variations) resulting in what appear to be scenes or images, on a cut sections. Wood Jasper, another variety, not only offers natural wood texture but also the feel of natural stone. Wood jasper combines natural beauty of both wood and stone. Although similar, Wood Jasper does not produce the pictures Picture Jasper is noted for when sliced..
Howlite, named for its discoverer Henry Howl is one of those minerals that is more famous for imitating another mineral than being used for itself. In most cases the other mineral is Turquoise, a phosphate gemstone. 
Although natural Howlite is always white or gray, it can accept dyes fairly easily and be dyed a turquoise blue. The look of turquoise is so good that dishonest dealers have been unfortunately successful at this hoax. In more honest circumstances, dyed howlite is an affordable substitute for turquoise carvings, beads, polished stones and cabochons. It accepts a nice polish and its porcelaneous luster is attractive and enhances even undyed beads and carvings. Unfortunately it has low hardness, but it still has a distinct toughness. California is the source for most all of the howlite trade where nodules of up to one hundred pounds have been found. In addition to the famous turquoise colored Howlite is dyed, it also can become a very bright red color to mimic red coral, or any other color in the rainbow.
