How do you find the right stone for you?
It’s really simple: Trust your instincts! Take your time looking at the stones. Which one do you like best at first glance? Often, that’s exactly the right one for you.
Maybe you really like a certain color—in that case, choose a stone in your favorite color. Or ask yourself: What do I want right now? Do you want to be more courageous, feel calmer, or concentrate better? Then pick a stone whose theme matches that.
There’s no right or wrong. The best stone is the one that makes you think, “I
really love this one!”
Just give it a try and take your stone with you as a little companion in your everyday life.

Information for Parents and Teachers
The Mole Craft Kits combine playful learning with a natural fascination for gemstones. Developed by Andrea Schmalzl, the founder and CEO of RelaxKids®, these special creative kits offer more than just crafting fun—they were formed as part of a holistic approach to learning support, relaxation, and stress prevention for children, but can easily be used without any specialized knowledge or prior experience. At Marco Schreier Mineralienhandlung GmbH, we carry these thoughtfully designed products, which help children discover the joy of creating while providing valuable educational insights—all without a lecturing tone.
Natural Stones for Child-Friendly Learning
The craft kits harness the special appeal that gemstones hold for children. The colorful, tactile minerals engage all the senses and provide an intuitive introduction to scientific topics. The tactile experience of different stone textures promotes fine motor skills, while sorting by color and shape playfully trains logical thinking. The combination of natural materials with creative design elements creates a holistic learning approach that engages both analytical and artistic skills.
Relaxation and Concentration in Children’s Daily Lives
The Relax-Kids craft kits were specially developed to support children in their daily learning. Focused work with the gemstones acts as a natural mindfulness exercise—attention is directed entirely toward the material and the creative process. This form of focused creativity provides a balance to children’s often hectic and overstimulating daily lives and offers valuable moments of calm. The finished creations become personal keepsakes that remind children of their abilities.
Versatile Retail Opportunities
These educationally valuable craft kits enrich the product ranges of various specialty stores. Toy and craft stores will find high-quality creative supplies here that stand out from mass-produced items thanks to their natural materials and well-thought-out design. Bookstores carrying children’s books use the sets as a meaningful complement to non-fiction books on minerals, geology, or relaxation techniques. Educational institutions and school supply stores appreciate the educational value and the combination of learning and creativity. For mineral shops, too, the Relax-Kids craft kits offer a perfect opportunity to appeal to younger audiences and spark their enthusiasm for the world of rocks. The child-friendly presentation provides age-appropriate access to a topic that otherwise often appeals primarily to adults.

Marco Schreier – A Fascination with Gemstones Since Childhood
Marco Schreier’s fascination with stones and gemstones has been with him since his earliest childhood. Even as a boy, he collected pebbles and special finds in nature with great enthusiasm—so intensely that even his grandparents’ car regularly had to serve as a “pebble truck.” His grandfather Rudolf, in particular, had a lasting influence on him: Through shared hikes, experiences in nature, and stories about the world of the mountains and their secrets, the foundation was laid for a lifelong passion.
A defining moment came when he discovered an alpine Rock Crystal from South Tyrol. For the first time, Marco Schreier recognized in it not just a beautiful stone, but the fascinating order, clarity, and Formation of a mineral. This discovery sparked his curiosity about the world of mineralogy—and what began as a child’s hobby grew into a serious interest. Books, microscopy, and field trips deepened his knowledge and enthusiasm.
This passion endured beyond his youth and continued to develop step by step. At just 16 years old, he began trading in minerals, thereby laying the foundation for his entrepreneurial career. What started as a small hobby eventually became a profession—driven by his unwavering fascination with gemstones.
To this day, it is precisely this enthusiasm that drives Marco Schreier: to understand and share the beauty, diversity, and Formation of gemstones. It forms the heart of his entrepreneurial endeavors and shapes the philosophy of Marco Schreier Mineralienhandlung GmbH.
