Michael Hill has been selling jewellery to Americans for nearly five years but the company has yet to crack the market.
The jeweller, which has eight stores in the United States after closing one earlier this year, lifted sales and revenues there to $US10 million in the 12 months to June.
But overall its US operations lost $US2.3 million.
Michael Hill chief executive Mike Parsell admits it is taking some time but says he's confident the company will achieve success in the United States.
"We're still learning that market. We're still experimenting with it. We're trialling new things. But we've learned a lot out of the US. So even though we're losing a small amount of money there, the benefits - both from the knowledge point of view and a financial point of view - have been significant for the business."
Overall, the company lifted its full year profit by nearly 10% to $40 million, thanks to higher sales in New Zealand and Australia.
Mr Parsell says the retail market remains challenging but he's "conservatively confident" the company can still grow the business.
