level 1

There are 2 beautifully made shiny and identically shaped pieces with one being silver and the other black (my pictures don't do them justice). The Diamond is the only Hanayama puzzle I know of which arrives with the 2 pieces completely separated (the Cast Loop by Vesa Timonen arrived with the pieces interlocked but in an incorrect configuration). Looking at them, it is obvious straight away how they are supposed to be linked together - there is a cutout on the back of each half diamond to accept the conical tail that protrudes above each half diamond. How to physically get them to lock together is another thing entirely!
