A British jewelry maker has launched a web site devoted to selling Thunder Bay amethysts.

Dave Austin said his company started importing the stones because of requests from people who use crystals in alternative healing practices.

"Apparently the crystal healers can pick up a piece of this amethyst and they can feel an awful lot of energy coming from it — which I personally don't feel — and they say that's down to it having an extra amount of extra composite minerals within the rock,” Austin said.

Austin said he's given samples to other so-called crystal healers and received positive feedback. 

"Some of the crystal healers that we've given it to, we actually gave them to [them] blind. We didn't tell them where it was from or anything like that," he said. "And we're getting very similar reports back from all of these people that it has a very high level of energy."

The healers tell him the stones are much more powerful than amethysts from other parts of the world, he said. 

Amethyst is a variety of purple quartz. The largest amethyst mine in North America is located in Thunder Bay. 

Austin said his web site has been up for less than a week and he has already sold several stones.

Customers are also interested in getting citrine clusters from Thunder Bay, he said.
