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!
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!)

We lived in the Berkshire Hills of western Massachusetts, and one summer weekend while out in the backyard doing kid things, something shiny on a dark gray rock caught my eye. It was a small, glittering gold square of metal.
