About 4C Minerals
Since 2008, 4C Minerals has been bringing natural stones from all over the world to your home. Our range includes luxury natural decorations, decorative stones of all sizes, collector and investment stones, products made of natural stones, as well as jewellery with natural gemstones.
Our mission
We offer natural stones in all their forms, both in our store and in our online shop. Every year we import new items from all over the world, and we make sure our range also includes unconventional, original materials.
We place great emphasis on the natural origin of every stone and on its correct identification and description. Thanks to many years of experience, mineralogical training and analytical capabilities, you can rely on the accuracy of our labelling – if needed, we will support it with a mineralogical analysis or an expert opinion.
Natural origin
Correct identification
New finds every year
4C Minerals was founded by Petr Černý, a mineralogist with a passion for stones. In our store you will meet his wife Blanka and a team who are knowledgeable in mineralogy, have a sense of aesthetics and share an enthusiasm for natural stones.
All team members are geologists by training or are well versed in minerals:
The abbreviation 4C stands for the four quality criteria by which gemstones are assessed. Our goal is to meet them with every stone we offer.
01
Colour
The hue, tone and saturation of the stone.
02
Clarity
How free the stone is of inclusions and blemishes.
03
Carat
The weight of the stone.
04
Cut
The proportions, symmetry and polish of the cut.
Our range includes only “4C specimens” – carefully selected examples of high-quality stones, from small pieces to unique museum specimens weighing over 200 kg.
