Guest Videos: Aquamarine


Aquamarine is a beryllium mineral like bertrandite or beryl, but its chemical formula is slightly different.

Who would suspect that the addition of a little iron or a change in the amount of aluminum would make such a beautiful difference!

Guest Videos: Chocolate and Geodes


OK, so chocolate and sugar aren’t technically minerals…they’ve still powered a lot of geologists on field trips.

In nature, you don’t know what’s in a geode until you cut it open. This can be a lot of fun, along with watching your YouTube views hit the million mark! (Note: They’re getting close to two million views now, and bless them, they haven’t monetized it. Thanks!)
