Amateur geologists from around the Eyre Peninsula have started their own club so they can explore each other's collections and hopefully find some unique rocks.
Eyre Peninsula Rock Hounds began two weeks ago after interest was sparked online.
Cowell rock hound Kristian Iversen started the Facebook page to attract more interest.
He said Eyre Peninsula had unique geology.
"There are some areas up my way where the strata is some of the oldest in Australia... and we get some world class minerals too, not to mention world class crystals as well," he said.
Port Lincoln rock hound Chris King has been collecting and crafting jewellery out of his finds on and off for 40 years.
He said while clubs had been tried before, he hoped this one will be a success.
"I found a fossil cockle shell out at Fishery Bay when I was 14 or 15….I now have thousands in my collection, it would be impossible to count."
He said there was a vast variety of stones in different locations in the region.
"Tumby Bay has more copper-based minerals, and crystals, Koppio has one particular stone I like to go collect called amazonite, which is a beautiful green stone," he said.
He said there was no harm in sharing the locations with people to generate interest in the hobby and the club planned to go on excursions to find new pieces.
"Nowadays with social media, it's opened up a whole new avenue...before you had to be introduced on a one-on-one basis, but now you're basically talking to the world," he said.
Club member Tanya Kelly said she was excited to share lapidary - the practice of engraving, cutting, or polishing of stones and gems - ideas, tips and collections.
"Finding a beautiful item and cutting and polishing it is exciting and rewarding...hopefully with a group formed we can set up some trips away prospecting together and share knowledge, skills and learn more about the geology around us," she said.
