MineralFest is a trade fair for minerals, fossils and jewellery that we at Conventio d.o.o. have been organising since 2016. By 2022, we had more than 10,000 visitors in Ljubljana. From 2023, MineralFest will also be held in Maribor, and in November 2024 we will be coming to Koper for the first time. We are proud and delighted to present a wide range of trade exhibitors, professional exhibitions and interactive workshops for visitors to attend at our events.
