Founded by the opal visionary Robson Wong, the journey at Rex & Co is deeply rooted in the intricate crafts of natural opal mining, excavation, and cutting.

Renowned for masterfully crafting large, flawless cuts from notoriously challenging boulders, Robson's work is a testament to his deep understanding of opal formations, where art meets science.

He is reputed to consistently break records, possibly holding the title for the largest opal ever cut.

At OPAL COLLECTIVE, we do more than cut opals – we unveil their hidden stories, bringing the earth's hidden colours to light.

Rex & Co has proudly provided state-of-the-art, natural Australian opals to over 200 brands, with several of these collaborations earning awards for their exquisite pieces adorned with our opals.

As an active participant in international jewellery trade shows and exhibits, Rex & Co showcases unparalleled craftsmanship on a global stage.
