Sunday Stamps: Geology

It's a stressful time right now in the USA,with corona virus everywhere it seems, and the peak of sickness still a week or two away.

To get away from this I looked in my computer files and found a bunch of scans of mineral stamps.  I'll share just two from Kenya.


Amethyst, in natural crystal form and polished as a gem, and


tourmaline, in a rock and also as a gem.  Amethyst is the purple form of quartz, and tourmaline is a complex silicate with boron and beryllium in its structure.

    Very attractive stamps. And always good to take a break from the coronavirus. Stay safe.
