The Challenge

In 2005, Wayne Sedawie was working in the opal fields near Lightning Ridge in central Australia, when he first recognised an opportunity to transform the traditional gemstone market with an online digital channel. He envisaged a 24-hour online sales channel connecting buyers with suppliers directly, giving buyers from around the world the chance to acquire genuine natural gemstones direct from the miner or wholesaler. He chose Coding Labs to bring this idea to life.

The Solution

Coding Labs developed a full-featured configurable auction marketplace for Gemrock Auctions combining enterprise-grade performance and a host of flexible trading options which maximise competitive tension, optimise price and drive sales growth.

The Outcome

Today, Gemrock Auctions is Australia's leading global marketplace for precious stones bringing together hundreds of verified sellers with thousands of buyers from over 135 countries. Gemrock Auctions is one of four specialist auction sites that Wayne operates on our marketplace platform.
