A true gift from the planet, Stromatolite is a billion year old sedimentary rock! These come the Eureka Quartzite formation in Nevada.
Stromatolites are an interesting reminder of the fascinating history of planet Earth and its earliest inhabitants.
They are amongst the earliest known forms of life on Earth and are a type of fossilized microbial structure found in shallow marine waters. Stromatolites typically form very slowly, with individual layers being added by colonies of microbes over time. These structures are important to geologists, as they provide insight into the history of Earth's earliest life forms and the environment in which they lived.
Stromatolites can be found all over the world in areas such as Australia, South Africa, and the Bahamas. In each region, they appear in different shapes and sizes, ranging from flat sheets to domes up to several meters high. They are distinct enough that researchers can use them to distinguish between particular periods of Earth's history, such as the Precambrian era or the Cambrian period.
Each piece is similar, though no item at Crystal Joys is exactly the same as every item is a unique stone that is non-fabricated. Slight variations in color, size, and shape may exist. Every item at Crystal Joys is true "one of a kind".
