The Hoang group has been operating since 1922. The management are fourth generation jewellers who have an extensive knowledge of the jewellery market both locally and overseas. In 1988 it was decided to open a store that would provide a range of diamond jewellery both ready made and bespoke that would cater to a discerning clientele. Thus Stefan Jewellers was born.

Stefan Jewellers operates from two locations: Stefan the Diamond Centre in the Hay Street Mall in Perth and Stefan Jewellers located in the Morley Galleria Shopping Centre. In order to remain competitive and ahead of current trends, Stefan Jewellers attend all of the major European trade fairs, and source their diamonds direct from the main diamond exchange buildings in Antwerp and Tel Aviv.

In addition to their unsurpassed reputation of sourcing only the finest white diamonds and setting them into contemporary hand crafted designs, in 2003 Stefan Jewellers added two European brands to their range, Bosco Giovanni Collection and Zancan , and was appointed the authorised distributor for Arctic Diamonds.
