Joan Rennick found a spearhead seven years ago at Cape Spear and thought it would be a good piece of jewelry, so she kept it, the Canadian Broadcasting Corp. reported.
"I put it in a little bracket and wore it around my neck for the last seven years," said Rennick.
The spearhead is about 13 centimeters long and is made of a dark rock.
Rennick subsequently saw a spear head in National Geographic that looked very similar to hers, and began to understand how old hers could be.
