They were fake. The Dutch got a fake rock. Many were also acquired from Antarctica, pertrified wood, and actual meteor fragments.
But by travelling out of atmosphere can you simulate them? Example can they grow Moon Rocks on the ISS. Maybe leaving dust, soil, rock exposed to deep space. Other experiments like possibly bombarding or colliding it with radiation or whatever.

Regardless many were fake. Holland's are.
