Olive green with hints of pistachio, cream and brown the black orb adds interest and a fall vibe that is spooktacular. This stone gets its coloration and swirls from colonies of fossilized algae. Technically not a jasper but stromatolite, this sedimentary fossil is billions of years old! I have photographs of the ring and with the wider band it may be an 8 that fits like a 7.75.
