Kambaba is an ancient algae fossil that's billions of years old. It's a pretty green color with orbital patterning in it that looks like some kind of alien being an eye or something that lives in a swamp! Kambaba, being a fossil, is connected to the life and death cycle and therefore is a good stone to use with past life work or death work. It also connects you to nature and the cycles of life. It's a calming soothing stone and it's certainly good for grounding.
