Turning goldfingers into silver
That's exactly what happened to Grafton resident Lyn Warner last Friday afternoon, after four of her 18 carat gold rings turned completely silver, apparently after washing her hands in the public amenities at the CWA Park in Coramba.
She said she was on her way from Grafton to Coffs Harbour through the back road when she stopped at the amenities, washed her hands and continued on.
"I was at Park Beach Plaza about an hour later, I looked down at my hand and all my rings were silver," she said.
"I just started trembling and crying. Then I was recommended to go and see Donaldson's Jewellers."
Ms Warner went and saw jeweller John Donaldson, who was mystified and called upon a second opinion.
"I've never seen anything like it - not how Ms Warner describes it," Mr Donaldson said.
The second opinion came from jeweller Wayne Franzi, who said in his 35 years he had never seen anything like it.
"It's very unusual. I never seen anything like that happen with water," he said. Ms Warner just wanted the situation sorted out.
"If it's doing that to my rings, what's it doing to kid's bellies?" she asked.
Coffs Harbour Water executive manager, Simon Thorne, said he didn't think the problem was anything to do with the water.
"I don't think it is the water, because that's the same water that everyone uses in Coramba - we would have complaints from everyone who wears a gold ring," he said.
"We carried a full test within the last month and everything passed 100 per cent."
"We test the water regularly, and we do that everywhere."
