I saw this at Harvards geology museum and was blown away. It’s amazing how the atomic structure of the mineral builds on itself over and over and over to the point where it completely encases the host rock it’s growing on. Then growing as a perfect cube to boot!
As if that weren’t amazing enough Topaz naturally colors as a translucent aquamarine blue. It can also take on Smokey orange and brown colors, but always remains translucent. This is why it’s considered a gem and has been highly sought after for generations.
Do you have any topaz jewelry? Ever seen it in this raw form?
