My Swiss collection of Odd/Unique stamps
Embossed and Odd shaped
Ammonites are spirally coiled fossils found on the fossil rich Swiss Jura Mountains.
Ammonites had an outer shell like a snail, but the inner part of the shell had chambers of the kind we can still see today in the living pearly nautilus.
(It is a silver colour stamp, the scanner couldn't able to capture the real beauty of the stamp)
