The Stefan Story
Celebrating a century of craftsmanship, Stefan Diamonds stands as a multi-generational family jeweller—built on 100 years of heritage, trust, and enduring success.
This legacy is not only preserved, but lived. Fiona Hoang and Joshua Reed remain closely involved in every aspect of the house—from design and sourcing through to the client experience itself. Their presence is felt throughout the boutique, where clients are welcomed into a more personal and considered environment, shaped by those who create the pieces.
Each creation begins with intention. Fiona designs every piece with a refined and disciplined aesthetic, while Joshua sources each gemstone directly from leading diamond houses in Antwerp, New York, and Tel Aviv. Together, their approach ensures a standard defined by rarity, provenance, and precision.
At the heart of Stefan Diamonds is a shared commitment to craft—where design, stone, and setting come together in quiet harmony, reflecting the sentiment and significance fine jewellery is meant to hold.
A Rare Distinction
Stefan Diamonds presents one of the most significant collections of diamonds and fine jewellery ever assembled in Australia, including an exceptional selection of rare pink Argyle diamonds. Finite in nature and unmatched in provenance, each piece reflects a standard of rarity and craftsmanship that defines the house.
Our story · Since 1922
A family of jewellers,for over a century.
From a small jewellery store in 1920s Saigon to our home on Hay Street, Perth — three generations, one family, every piece made by hand.
Prologue
Every Stefan piece carries a little of the hundred years behind it — a story of two families, three countries and a love of beautiful things, handed down from one generation to the next.
Chapter I
Where it began
Our story begins in Saigon in 1922, in the final years of the Nguyen Dynasty. French influence was reshaping the city's culture and design, the botanical gardens were still saplings, and the Áo Dài was evolving into the elegant silhouette we know today.
It was here that Mr Hoang opened My-Dzung — a jewellery store that blended western design with the craft traditions of south-east Asia. In a time when currency was unstable, gold was the commodity families trusted, and every gold bar and leaf that left the store carried the My-Dzung name.
Saigon in the 1920s, and Mr Hoang, who started it all.
Chapter II
Two families, two countries
Across the ocean in 1955, Joshua's father began his apprenticeship at Rodds Silverware and Jewellers in St Kilda, studying watchmaking at RMIT by night. It was the beginning of a lifelong devotion to the craft — one he would one day pass on to his son, who grew up working alongside him.
By 1980 the Hoang family had made a new home in Perth and opened My-Dzung once more. Their south-east Asian-inspired jewellery was soon worn by local women with the fashions of the day — androgynous pleats, wide-legged trousers and belted coats.
Two weddings, two families — 1955 and 1980.
Chapter III
Becoming Stefan
Having grown up around her family's stores in Melbourne, Vietnam and America, Fiona opened Stefan Diamonds in the Perth CBD in 1988. Her designs carried a European elegance, inspired by time spent in London, France and Belgium.
By 1998 Stefan had stores in the Hay St Mall, Morley and Fremantle, and had become known for exceptional large diamonds and timeless statement pieces. A year later Joshua joined the business, travelling to Antwerp to hand-select the stones himself — and the two families' stories became one.
Our heritage is a collection of moments that string together to tell our story.
Chapter IV
The house on Hay Street
In 2009, days before Valentine's Day, a remarkable 9.00 carat diamond found its new home. Two years later Stefan moved into its flagship in the historic Gledden Building on Hay Street — the home we still welcome you to today.
Along the way we created a tiara of more than 650 white diamonds set in 18ct white gold for the Queen's visit, became a proud sponsor of Polo in the City, and began supporting the causes closest to our hearts, including Rafiki, Toy Bank and Brainchild.

Chapter V
The next chapter
Today Stefan is still, above all, a family. Fiona designs every piece, Joshua travels the world to hand-select every stone, and since 2022 their daughter Sophia has worked beside them: on the boutique floor, at the trade fairs in Hong Kong, and at the design table, creating new collections with her mother.
A century on, the name above the door has changed, but the promise hasn’t. Every piece is still chosen by family, made with care, and placed in your hands as if it were our own.
The family today.
