Peanut wood jasper also known as petrified wood or peanut wood opal, is a type of fossilized wood that originates from the Cretaceous geological period around 100 million years ago.
It is usually dark brown to black in colour and recognized by its white-to-cream-color markings that are ovoid in shape and about the size of a peanut. It is primarily found in Western Australia, specifically in the Kennedy Ranges and Lake Indoon areas.
It belongs to the cryptocrystalline quartz group and has a hardness of around 7 on the Mohs scale. Its texture can range from fine to medium-grained, and it has a vitreous to greasy luster.
Peanut wood jasper is formed when ancient trees are preserved and replaced by silica-rich groundwater. The wood cells are gradually replaced by chalcedony, which gives the material its characteristic appearance. The name “peanut wood” comes from the small, peanut-shaped markings that can be seen within the jasper, resembling little nodules.
Peanut wood jasper is highly valued for its unique appearance and can be useful in various decorative ways. It is often cut into cabochons, beads, and small sculptures for use in jewelry and ornamental objects. Its distinctive markings make it a popular choice for collectors and those seeking unique gemstone.
Peanut wood Jasper is not a globally recognized or commercially valuable as some other gemstones, its scarcity and unique beauty can increase its market value among enthusiasts. Prices for peanut wood jasper can vary depending on the size, quality, and demand in the market.
