Exports also grow with plans to launch Emozioni internationally.
Hot Diamonds has announced a 29% increase in domestic sales of its jewellery for the 2012 to 13 period, with plans to grow its coin concept collection internationally.
The British brand has also reported growth in exports, up 16% year on year, despite what it describes as a "challenging global market".
Hot Diamonds head of commerce Adryan Cresswell said: “We are satisfied with the progress that we have made during 2012 to 13 in the face of some pretty adverse economic conditions.
"We have very exciting domestic and international plans for 2013-14 which we expect will help us maintain this level of growth during the next financial year and beyond.”
The brand launched its Emozioni collection at The Jewellery Show in February – a range of interchangeable coin concept jewellery. Hot Diamonds managing director Sanford Simpson said Emozioni had been taking shape in the UK market, opening 70 doors in six weeks.
Simpson said: “We expect to open a further 180 doors before the end of June 2013 [and] we will also be launching Emozioni in four key international territories in the coming months, including the USA. This will provide an important new revenue stream for our retailers throughout 2013-14 and beyond."
