Diamond Exchange is famed for its alluring array of diamonds in both their flagship showrooms at the upmarket Collins Street in Melbourne and the iconic heritage Georges Building in Sydney. Less known, but equally impressive, is the retailer’s 125-year history spanning four generations which began in the Victorian town of Ballarat. Currently managed by brothers Jamie, Jeremy and Sam, Diamond Exchange was traditionally an online-only business model that operated successfully for over a decade.

In 2016, Diamond Exchange identified an opportunity for the business to make a transition to a physical entity. The Thomas family partnered with greater group and “The Lab”, our build arm to design and implement their first boutique in Melbourne which was followed by their second store in Sydney. Inside the walls of both spacious and light-filled boutiques bring a new type of luxury retail experience to life by combining traditional elements with modern design features.


Despite presenting greater group with a number of challenges… they delivered a beautifully designed and immaculately appointed showroom which exceeded our expectations.
