River Gemz specialises in expertly hand-crafted jewellery made from quality natural Australian solid
opals, cut into either freeform shapes or calibrated to maximise their unique attributes.

The River Gemz shop is in the picturesque town of Mannum, along the banks of the beautiful Murray River in South Australia.


We are excited to launch our wooden homeware (including clocks, cheese & cutting boards) made from locally sourced pine wood from Crafers, South Australia.

Each item comes with inlayed Australian crystal or white opal chips.

Handmade by us in our workshop here in Mannum.

We only have a limited supply so do not miss the opportunity to snatch one up for yourself!

We would like to acknowledge the Ngangaruku people who are the Traditional Custodians of this land. We would also like to pay respect to the Elders both past and present of the First Nation and extend that respect to other Aboriginal people present.
