It is a type of petrified bogwood found in the McDermott area on the Nevada/Oregon border. The stone is known for its earthy tones, including shades of green, blue, brown, red, and yellow. It has a Mohs hardness of 6.5–7, making it durable for use in jewelry and decorative items. The material is believed to have been formed between 11 and 15 million years ago when volcanic activity covered the area, and minerals from the volcanic ash replaced the organic material. It is often used for cabochons and other lapidary projects.
