P90 Stromatolite Fossil Pendant
Shoppers didn't know what the stone was but most people I've asked think the stone is a stromatolite fossil. That being said, the other guesses were jasper, agate, and petrified wood. No matter, what it is, the I loved the stone and the richness of it.

Precambrian stromatolite is the oldest of all fossils, and with much labor (cutting and polishing), it is most beautiful. The banding that commonly appears in stromatolite is a record of the growth patterns of colonies of microorganisms, principally photosynthetic cyanobacteria, but also other Eubacteria and the Archaeans. The colors that are often expressed are the result of the interaction of biological and sedimentary processes, together with subsequent chemistry and mineral exchange.
