Francesco and List,
Amazon (which has many European
outlets and delivers to over 50 European
countries) has a very nice 1 cm scale
cube of gold-plated tungsten carbide
with top, bottom, north, south, east,
and west well-marked, made by a
company named "Scale Objects" for
US$28. As it's of negligible weight,
air shipping should be minimal. The
cube is beautiful, useful and quite
precise (I checked it with a micrometer).
Tungsten carbide has a low coefficient
of expansion and is quite hard.
Now, all I need is a large newly
discovered meteorite in situ, ready
to be photographed...
