About Us - The Team, The Goal, The Dream, Our Opal & Gemstone Family

From the earliest days of our business in 2004 we have gone from a ‘one man show’ to a international specialist team which continues to grow our Opal and Gemstone business.  We are lucky enough to have years of experience in our team members from many industries and backgrounds allowing us to draw on that expertise and combine it with our passion for Opals and Gemstones.

About Us - Wayne Sedawie

After meeting his mate Chris from Opal Rush, Wayne was hooked on Opals. Over the years he has had shares in Opal mines, operated Opal cutting factories and jewelry factories overseas and has cut over 200,000 Opals himself. His growing passion for Opals made him realise he needed to bring these amazing stones to the people of the world.
