Named after the Kona Hills south of Marquette County, Michigan where it is found. Kona Dolomite is an ancient
rock in which formations of fossil stromatolite (blue-green algae) occur. The stone is between 2.1 to 2.2 billion years old.
These stromatolite formations are from some of the first life on earth. These fossil formations are found in the lower eras
of the Middle Precambrian Period.
Because of its great age, and due to the many trace minerals present, kona dolomite can be found in a
wide variety of shades including pink, brown, yellow, cream, red and orange with shades of brown, cream, gray and black mottling,
banding and lacing.
Mohs hardness ranges between 3.5 and 4. All photos on this page were taken of wet material. If
