It decays spontaneously into nitrogen 14 N. Thus, the growth pattern of a tree of a known age can be used as a standard to determine the age of similar trees. Scientists can determine an approximate age for a layer by examining which species or genera of animals are buried in it. I sent some pictures of the ring to auctionata, to be fair to them they did say it could be historical cultural heritage, but the only deal with very high value items.

I would be interested in selling it.
Relative Dating vs. Absolute Dating: What's the Difference?
Is the Universe Made for Life? Invisible, high-energy particles that constantly bombard Earth from all directions in space.
