OUR HISTORY

The Costello group is an Australian-owned operation that has specialised in Australia's unique gemstones for three generations. The group was first established as the Koala Opal Centre in 1955, with the founder John Costello pioneering the export of Australian rough opal to Japan. The next generation of the Costello family, under the leadership of Michael Costello, was responsible for the establishment of retail outlets in the major gateways of Sydney and Perth.

The third generation of the Costello family has continued the tradition, expanding the group's operation to include further retail outlets in Perth and Sydney. In 1994, Braham Costello assumed responsibility and ownership of the Perth arm of the operation while brother Jamie Costello took over the Sydney operation. It is Braham and Jamie's aim to continue to honour the family tradition of offering clients high quality Australian gems and jewellery complimented by premium customer service.
