Dinosaur Bone
Dinosaur Bone is a tantalizing stone with a history and look unlike any other non-petrified stone. Not a true “stone”, Dinosaur Bone is created from fossilized dinosaur bone that has had part of the bone cell structures replaced by quartz, similar to petrified wood. Colors range from earth tones in deep mahogany and chocolate brown to black, with some rarer specimens in peachy coral to bright reds and golden-yellow, with splotches or mottled patterns in red, blue or yellow. Color is determined by the impurities in the nearby sediment when the bone is fossilized. The mottled appearance is similar to some obsidians and jaspers. Because of this thick ‘dried riverbed’ look, Dinosaur Bone is usually cut into cabochons with high domes to show off its interesting surface.

Highly polished, matching Dinosaur Bone cabochons make interesting earrings and pendants, and this fascinating stone is a good candidate for men’s jewelry, particularly rings and cufflinks. Patterns in the brown, black, brick red or gold-brown background may be made of round or ovals, swirl type, or have more of a striated pattern. Lacing between the patterns is generally lighter in color than the background, but on the rarer reds and golds, outlining may be black or brown and with finer, smaller cells.

Dinosaur Bone may be set in gold or silver and is popular in abstract or free-form designs. The earth tones and organic nature of this translucent stone add to casual wear and natural fabrics. Eggs, spheres, and rounds (balls) are popular for display and collections. Part of the value of this fossilized stone comes from its limited supply. Dinosaur Bones are not allowed to be removed from government protected regions, such as U.S. state or federal lands.
