GemRockAuctions: About Us

Wayne and Estela Sedawie started cutting their own gemstones in their home in Perth over 18 years ago. Moving to Queensland they established Opal Plus, a wholesale opal business, and began selling around Australian and in New Zealand, USA and Japan.

The step up to the global market with the discovery of ‘online auctions’ came with a steep learning curve in computer technology and the online world. The move proved a great success and, using eBay as their auction facility, Opal Plus became the largest online opal seller within a year.

Today Wayne and Estela run OpalAuctions.com which boasts over 60 verified opal sellers from around the world, and 44,000+ auctions each day. It’s one of the largest opal collections online.
The launch of GemRockAuctions.com  has seen the same rapid success, offering customers a secure online shopping experience with a wide range of wholesale gemstones, jewellery, minerals and unique treasures from around the world.
