How coincidental that I have sent a stamp with a mineral (quartz) in one of the two postcards from Morocco that, I'm afraid, are still in their way...!
It arrived in decent time, about 8 days i think. And it have me a perfect stamp for later in the alphabet ;)
Beautiful stamps! My late grandmother collected stones / minerals and I think thanks to her I love to see stones - even common ones are special :-)
By the way, I think this collection is a delight for the founder of Sunday Stamps (if I remember well, she once wrote she likes minerals but/and minerals on stamps are hard to find)
I think the way they are displayed against the white has a striking effect.
Wow, these mineral stamps are fascinating! Croatia has some great mineral stamps issued, so for the founder of Sunday Stamps, I may have it on my list for my next trip, I would just need the address :)
I like how these are presented as little statuettes.
As I studied geology as part of my university course I found this stamps fascinating - I even recognised some of the minerals.
Love the combination of typeface and mineral, beautiful colours. Look like they could be awards for 'best in show'.
