Leonards: A History

The Leonard family have history rich with experience in luxury jewellery. Their heritage and name can be traced back to the mid-19th century to Tessier’s of London. The Leonard family have been expert craftsmen passing down trade secrets for generations and still providing the highest quality work today.

The family immigrated to Australia in the early 20th century and set up a small store in the family home at 110 Darby Street, Cooks Hill in 1932.
The business has continued to flourish since the 30’s in the same location for over 80 years. While it may no longer be a family home, Leonards Jewellers remains just as authentic, selective and professional as when the store opened many years ago.

In the 1980s the Kimberley Argyle mine opened. This was the only mine to ever successfully exploit a lamproite vein and will likely be the only mine to ever do so. With a passion for quality, luxury and rarity, the Leonards decided to expand their repertoire and additionally started to deal in the unfathomably rare, Argyle Pink Diamonds. 35 years later, they have the largest collection of Argyle pink diamonds in Australia.

As of 2020 Leonards Jewellers expanded even further and began stocking De Beers diamonds. De Beers are the pinnacle of diamond quality representing the top 1% of white diamonds globally. Leonards Jewellers is the only certified De Beers agent in NSW and have the largest collection on site in Australia.
