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

Wayne Sedawie was introduced to Opals in 1992 by his brother Paul from Seda Opals, who mines at Lightning Ridge in New South Wales, Australia. 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. 

About Us - Paul Sedawie

In September 2004 Wayne founded Opal Auctions. The goal was to offer Opals direct from Opal miners and wholesalers direct to opal buyers all over the world. 13 years later over 330,000 Opals have new homes in over 184 countries.
