Heidi's high jewellery affair began in childhood, nurtured by the love for jewellery instilled by her grandmother, who crafted special pieces to celebrate her birthdays. This early experience ignited her passion for design, architecture and love of interiors. Travelling with her family to Boston and Asia from a young age, she was surrounded by exquisite gems from renowned jewellers sparking her ambition and dream to create Heidi & Hart.

Her professional journey took flight in the early '90s when Heidi studied gemmology in Sydney, gaining an intimate knowledge of the industry. At Autore Pearls, Heidi forged lifelong connections with diamond and gem merchants as well as retailers, working at both local and international jewellery trade fairs.

 In 1999, Heidi  founded Australian Pearls, collaborating with Harper's Bazaar on mostly editorial features that showcased her unique vision for jewellery for years. 

Recognising an opportunity in the market, Heidi cultivated deep relationships with pearl farmers, graded Australian South Sea pearl harvests, and reimagined estate jewellery from renowned auction houses.

Her expertise and love for diamonds culminated in 2014 with the acquisition of the rare, world-renowned Argyle Tender Diamond Lot 1 Hero Diamond, "Cardinal." This remarkable achievement solidified her reputation as a leading force in the jewellery industry.
