"But, for example, a heavy bracelet that was $2000 to $3000 is now $4000 to $6000 - there may be some resistance at that price."
He said it was a good time to get heavy gold jewellery revalued as owners could find themselves badly underinsured if they lost it.
Grant Partridge, owner of Partridge Jewellers, said the price of a man's wedding band had more than doubled in the past two or three years. "They're still going to get married - they're just going to have to pay more."
The firm had always sold 18-carat wedding rings but was considering using nine carat gold to cut prices.
Partridge said he had a bracelet in stock with a price tag of $2700 which would be worth more than $7000 if it was melted down.
The appreciating gold price had increased the value of his stock but not helped to sell more.
In India high bullion prices cut demand as the busy wedding season resumes later this month.
Gold jewellery is an essential part of the dowry parents give daughters at weddings. Peter McIntyre, of ABN Amro Craigs, said investors were buying gold because of the disdain for most currencies.
"We think gold has a bit to run and don't really see a bubble until about US$2000 an ounce," he said.
"They're extremely volatile times and some institutional investors are thinking a zero return is better than a negative 10 [per cent] return and that's what it comes down to at the moment."
Buyers needed to consider the value of the New Zealand dollar as well as the price of gold. The idea is to buy on a high kiwi dollar when gold prices are falling.
