The Mary Ellen is fascinating to look at, especially with a magnifying glass. I love its water swirl patterns. It sent me into a few days of watching all the documentaries I could find about supercontinents and continental drift.

Ethically Sourced

Mary Ellen Stromatolite from United States

This Mary Ellen Stromatolite is from the Mary Ellen Mine in Minnesota, USA. It was originally an industrial mine for Iron Ore, but today the primary product is Stromatolites for collectors.  The current mine has a low environmental impact.

This lapidary drum tumbles stones in Cape Town, South Africa. It is a family business, founded by a father and passed on to his sons. Factory workers have safe conditions and are paid fairly. The lapidary sells primarily at two gemshows, one in the United States and the other in France.

I have been doing business with this source since 2014. They are the oldest tumbling company in the world and have more varieties, in more sizes, than any other known source. The company started in California in the 1950s and was eventually bought by a British immigrant who had young sons. Eventually the company moved to South Africa in order to be closer to the source of their best-selling stone and to have the legal rights to export it. The company is now run by the sons and their childhood best friend.

The current owners personally visit many small and large mines. To connect with artisanal miners in sub-Sahara Africa, they work with local Gem Dealers who travel far into the bush to buy from part-time miners. The majority of these Gem Dealers are women. Some, but not all, of their stones are labeled with country-of-origin. For those that aren’t, I ask the owners directly. As I’ve learned more about mining practices in individual countries, I have become increasingly selective about what I will purchase from them. However, they remain my preferred source for most of the stones I sell from sub-Sahara Africa.

Mary Ellen Stromatolite Healing, Mineralogy, and History

Published July 2015  •  Updated February 2024  •  Read Time: 6 minutes
Stromatolite is a fascinating fossil that shows us the very beginning of life on earth.  While it may look like nothing more than swirls and spots, it actually is a fossilized version of a colony of blue-green algae.  In a few precious locations, “living rocks” have been found where the algae colonies are still growing and thriving.  Two of the more accessible locations in which to see them are Shark’s Bay, Australia and the Bahamas.  Even though it is generally considered an ancient organism and an ancient fossil, new algae colonies can form today in the right conditions.  Stromatolite encourages us to love biodiversity and to be fiercely protective of the planet.

    This is a fascinating stone. With its red swirls in between metallic speckles, it gives the impression of looking into a foreign world. I just love it! Thank you!
