Rudolph Minerals has a constantly fluctuating inventory of incredible minerals that they bring to every show. And one, very important, thing to keep in mind is that every piece on display is not just a randomly, nice mineral, it was actually evaluated and purchased by Scott Rudolph for his personal collection. Prior to every show Scott Rudolph and Mat Duren go through Scott's collection and decide which pieces can be brought to the show and offered for sale. These choices change every time they do a show so we're always exposed to new and different excellent minerals.

In this clip we meet with Mat Duren and take a quick peek at some of the fantastic minerals they've brought to the 2023 HardRock Summit INCLUDING a literal piece of Tucson history.
