Mineralien weltweit is an independent mineral shop and educational platform run by geologist and mineral collector Paul Krause. It offers carefully selected collector minerals from classic localities around the world, with an emphasis on precise provenance, geological context, and honest descriptions of each specimen. The online shop features individual pieces such as emeralds, calcite, apophyllite, gypsum, agate, quartz, and other minerals from countries including Colombia, India, Mexico, Poland, Norway, Germany, Morocco, and Spain. Some specimens were acquired or collected during the owner’s own travels and field excursions.

In addition to online shopping, the brand presents selected pieces in a showroom and provides personal, knowledgeable responses to questions about specimens, mineralogy, and localities. Its blog shares articles on geology, mining, mineral regions, travel, and the stories behind notable finds, including Colombian emerald districts and regional German specimens. Mineralien weltweit also highlights localities by country and offers a newsletter with updates on new specimens, destinations, and mineralogical topics. Its approach combines specialist knowledge with transparent sourcing and thoughtful selection for collectors.
