A Danish friend once carved this Siberian larch bowl for me; since about 1997 it is filled with stones from Great Britain, there's one from England, one from Scotland, one from Wales and one from Ireland (ok, not GB but, dunno if it is from N.Ireland or Eire)... the one underneath the shell is from Samos, and a little one with a stone inside the stone is next to a special hazelnut, 2 walnuts are there too, the right one you can open, it contains a message in orange letters saying, "ICH LIEBE DICH"
p.s.: the England stone is the smallest one :D
