Minerals and fossils
The description of the contents comes from a 1999 events listing. It tells you what the name was used for at the time, not what can be seen today.
A listing for visits by appointment
Museumgids Nederland lists visits by appointment. Whether that listing is still valid has not been confirmed.
The right location
When you make contact, check that it concerns De Siersteen in Oostwold; there may be confusion with another place name.
