Queen of Gems Jewellery Design Awards
The Queen of Gems Design Awards held its inaugural ceremony in 2006 as an initiative of Winton local business owner Mary Pearce. Entrants from across Australia showcase the Queensland boulder opal in all its splendour and the creativity of their design and manufacture. Since then, the annual competition has increased to receive entries from Australia-wide and internationally. New categories have been included, such as Wearable fashion, Objects & Art, and the new jewellery designers using CAD/CAST/CAM.
Everyone is welcome to enter, from beginners to professionals.
