Holloway Diamonds

Garry Holloway, owner and founder of Holloway Diamonds, is an award-winning jeweller and creator of the Ideal-Scope and the Holloway Cut Adviser (HCA) system. He left a career in geology to follow his instinct and begin Holloway Diamonds.

Today Holloway Diamonds is at the forefront of diamond innovation. The patented HCA system has been used to grade the cut quality of billions of dollars’ worth of diamonds. His diamond-cut consultancy has strong alliances with leading international diamond researchers and websites.

In addition to the company’s push to continue to innovate gemstone technology for the next generation, Holloway is also devoted to corporate social responsibility. Holloway is the first and only company in Australia to have undergone the most rigorous corporate social responsibility audit in the world. We ensure that all of our diamond cutters and suppliers avoid conflict diamonds by using the standards set into place by the Responsible Jewellery Council. We remain committed to ethical, social and sustainable environmental practices for the jewellery industry. To that end, Holloway Diamonds is a Member of the Responsible Jewellery Council and supports the implementation of the Code of Practices.

Holloway Diamonds has called Melbourne home for 36 years and we plan on providing quality products, tailored manufacturing, custom jewellery design and our core values of trust, service and specialisation for many more generations to come.
