Named after the Kona Hills in the 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.
