We look forward to seeing you again in July for the summer in-house exhibition.

27.03.2023: Thank you very much for your donation!

We were pleased to invite you to the in-house exhibition for spring salad or spring rice - with falafel or chicken.

A total of €1258.33 was collected in the donation pots, which we are forwarding to the association on your behalf.

Thank you very much for this!

20.02.2023: Sparkling things from Thuringia

Still on its way to us, but arrived before the in-house exhibition:

Sparkling Pyrite in black slate from the historic slate mine in Lehesten in the Thuringian Forest. Slate has been mined in Lehesten since the 13th century, split and processed into slate sheets, roof and wall coverings. Specially selected raw materials are processed into Smooth Stones, pencil stones, jewelry and more.

More information about a visit to the site and the exciting history of pyrite slate

16.02.2023: Easter in sight!

Wasn't it just Christmas? And Easter is just around the corner! From today, it's only seven weeks until Maundy Thursday.

Now that a large shipment from Hong Kong has been processed, it's on to Madagascar! There are still many boxes and crates waiting to be unpacked.

But you don't have to look for the gemstone eggs at the in-house exhibition - just look at the Madagascar tables and find eggs made of blue calcite, Septarian, Rose Quartz extra and other types of stone!

15.02.2023: Lectures with Monika Grundmann

The topics for the popular in-house exhibition lectures with Monika Grundmann have been confirmed! From Thursday to Saturday, the topics will be Gemstone Water at 11 am and Awakening Inner Strength at 3 pm. The lectures will take place on the second floor of the mineral shop. Free admission, no registration required!

11 a.m.: So simple - so good: Gemstone Water
Can you taste the difference between "joie de vivre" and "serenity"? What does the detox water "Fountain of Youth" taste like? We should all drink more - this piece of wisdom is banal, but always difficult to put into practice in everyday life. Water energized with gemstones is a small but effective way to enjoy water more.

Monika Grundmann presents the various ways of preparing Gemstone Water. Which method has which advantages? Which water is ideal for yoga? You will receive answers to these questions and many tips on preparing gemstone water in the lecture.
3 p.m.: The power is in me - strengthened through spring
Spring is the time of new beginnings - not only in nature, but spring is also a good time to implement ideas and carry out projects. However, sometimes things don't go as smoothly as expected and resistance and problems arise. In this talk, Monika Grundmann shows us how we can awaken our inner strength and stay on the road to success.

14.02.2023: Valentine's Day

Gemstone hearts are not only a popular gift for Valentine's Day! Mother's Day, weddings or wedding anniversaries - or simply as a heartfelt thank you - are also popular occasions for giving.

New arrivals include extra-large Rose Quartz hearts up to 10 cm in size and weighing 0.5 kg, as well as Amethyst Druzy hearts in various sizes and qualities.


10.02.2023: A warming greeting from India

Brrr....

It's still quite chilly in Osterholz and occasionally it even snows a little. So the new drilled Moonstones in orange-pink came just in time to spread a little warmth.

09.02.2023: Precious chalcedony

Our jewelry designers have also been inspired by the new strands:

They are currently creating beautiful gemstone necklaces from precious chalcedony and many other types of stone.

30.01.2023: New strands for a creative spring

New strands have arrived again with the latest sea freight from China! Among them were Mother of Pearl beads and Tumbled Stones made of Tsavorite, a rare green garnet.

Be inspired by the variety of colors and shapes!

27.01.2023: Tickets available now!

Please register for your preferred day so that we can plan the Spring House Fair optimally for you, e.g. the food from the Blessing food truck.
