Our 4C minerals store has been bringing natural stones from all over the world to your home since 2008. In our selection we have luxury natural decorations, decorative stones of all sizes, collector’s and investment stones, products made of natural stones, but also jewellery with natural precious stones.



We offer you natural stones in all their forms, either in our store or in the e-shop. Every year we import new items from all over the world, we try to ensure that our offer also includes non-traditional, original materials. We emphasize the natural origin of all stones, their correct designation and description. Thanks to many years of experience, mineralogical education and analytical possibilities, you can rely on the accuracy and truthfulness of the labels of stones and jewellery, which we will corroborate, if necessary, by mineralogical analysis or expert opinion. We try not only to make our customers happy with our products, but also to share with them our knowledge of mineralogy and stones.
