About Opals Down Under

Opals Down Under is a family business which was started by the Stein family on the Sunshine Coast in Queensland, Australia since 1985. For over three decades, Opals Down Under, now under ownership of Opal Artisan, Scott Coggan, has cut, supplied, and valued amazing Australian opals from the different fields.

Our online opal catalogue is updated frequently and gives you the opportunity to buy opal knowing it has been cut by one of Australia's leading opal experts.

We started out mining opals in 1962, have been cutting opals professionally since 1963, and selling opals on the internet since 2003. We have an excellent reputation in the opal industry and an extremely good customer satisfaction record. We offer a money back guarantee on all our internet purchases, however our clients rarely send opals back as our photographs represent the opals fairly and accurately. With a wealth of experience, expert skill, and opal knowledge, you can count on us.

Our business is based on integrity and honesty - we operate under Christian values and principles and set extremely high standards for ourselves in the areas of customer service, integrity, and professional workmanship.

Our Story

Special report: Love on the opal fields - read how romance blossomed on the outback opal fields for Opals Down Under's founders!

A young adventurous Austrian emigrated to Australia in 1961 at the age of 21. Young Immo Stein was a blacksmith by trade, the son of a Salzburg silversmith and seamstress. However he left his family and his beautiful home country to seek fortune and adventure in the remote and mysterious great southern land. After working for a while in the Snowy Mountains Scheme, Immo travelled extensively throughout Australia.


In 1962, his adventurous spirit took him to Andamooka, South Australia, where he started mining opal and became totally fascinated by this beautiful gemstone. Immo grew to love the simple and hard-working lifestyle of the Australian opal fields, however he never did find the millions of dollars he was after.

In 1963, Immo started cutting opal, and he continued mining for about ten years. During this time he also mastered the skill of opal cutting.

In 1969, he married Louise Davies, a waitress and they moved to Coober Pedy. They had two children, Danielle and Heidi, and lived in an underground 'dugout' for about five years. After moving to Adelaide for a year, they travelled around Australia in a 31 foot caravan, cutting opals from a mobile workshop and supplying opals to gem dealers and jewellery stores. It was during this time that their son Adrian was born.


In 1980 they moved to Queensland and set up their first opal shop on acreage north of Gympie. The businesswas run from their Queenslander home, with Immo cutting the stones and Louise serving customers. The business grew rapidly with enormous interest from overseas visitors in their opal cutting and workshop display.

In 1985, they took a gamble and built Opals Down Under, on Queensland's Sunshine Coast. Immo and Louise dedicated themselves to raising their family whilst also running a successful business. Immo began studying gemmology and, in 1987, became a qualified gemmologist.  The business began to draw tourists from around the world, and Louise continued to enjoy serving customers and raising her young children. Immo continued to perfect his skills in opal cutting whilst still travelling to Australia's opal fields regularly to buy Australian opal in the rough for cutting.

In 2017, Scott Coggan (who had managed the business for fifteen years), took ownership of Opals Down Under, with the Steins heading into, and enjoying, retirement.

Since then, Opals Down Under has gone from strength to strength, while still maintaining the work ethic and integrity of a small family business. 

Our staff members are all highly trained, friendly professionals who enjoy working with Australia's most amazing gemstone. Owner/Opal Artisan Scott Coggan is an Australian opal cutting specialist with two decades' experience, and is considered one of the finest opal cutters in Australia.
