What you have here is the fossilized resin of the Kauri Tree, a rare piece of history from Kauri Trees long gone.
It’s an amber not a stone so:
A soft cloth can be used as a buffer (Using sideways, not circular motions) to maintain the gum’s original shine.
Treat your piece as a precious gem and it will last forever.
