Diamond Guild Australia has announced the judging panel for the 9th Australian Jewellery Design Awards.
Regarded as Australia’s most anticipated and sought after jewellery design event – the Diamond Guild Australia Jewellery Awards will be held for the 9th time in 2026 and will showcase the best of Australian jewellery design talent to both the trade and wider consumer market. The Awards are open to all jewellers and designers working within the retail Diamond Jewellery industry to test their talents across eight categories, each focussing on different aspects of the beauty and versatility of natural diamonds
Katerina Perez
After training as a gemmologist at the Gemmological Association of Great Britain while working for Tiffany & Co., Russian-born, Paris-based Katerina spent time at Chaumet, Asprey and Boghossian, gaining sales and management experience. In 2011 she changed careers, becoming a freelance journalist and content editor. The reason behind this sudden switch? The customers she had met only wanted to know about the carat weights and prices of jewels, whereas Katerina was much more interested in the inspiration, original ideas, craftsmanship and design. It was this detail she wanted to share with the world. To achieve her goal, she founded her eponymous website and Instagram platform in 2013.
As one of the first writers to bring high jewellery online, Katerina is highly regarded for her expert opinions on the outstanding designs she encounters during her travels. Her words have appeared in many titles, including Vogue, L’Officiel and Robb Report, and she’s often called upon to provide thoughtful introductions for books, brochures and exhibitions. Her favourite part of the job? Championing the work of talented jewellers across the globe. From established brands to fledgling designers whom she has personally scouted, Katerina shares their creations on her channels for her community of jewellery aficionados.
