A juxtaposition of beauty and science: Stromatolites
from the Mary Ellen Mine in Minnesota, commonly known as Mary
Ellen Jasper, are prized by jewelry-makers owing to the often
stunning color displays. These are polished all-around, with
the polishing bringing out vivid crimson reds, greys and blacks,
and occasional greenish tints. polished to make a
 stunning
display from any aspect, and exhibits vivid a dark grey with
greenish tint, Collenia growths of crimsome red, an unusual color
for the site. Scientifically known as Collenia undosa, the micro-organisms
involved were likely to have been photosynthetic bacteria that
were busily expiring oxygen during deep geological time that
would ultimately constitute the modern atmosphere on earth (of
the Proterozoic Era) when the Earth rusted. Gorgeous jewelry
pieces could be made from these. Cyanobacteria mediated the production of these
some 2,300 million years ago, when single cells prokaryotes dominated
life on Earth..Stromatolites have persisted to the modern day in such places as Shark Bay, Australia where they continue their billions of year's old lifestyle. While this piece would make a fine present for any natural history buff, anyone who appreciates art would also be glad to get thus wonderful specimen of the Earth's oldest fossils as a gift. |
