This cast diamond is only ratted as difficulty 1, so the easiest, but I am sure you will take more time to solve it than what you first expected!
Usually cast puzzles come attached to each other and your goal is to disassemble them. But here, the 2 pieces of the puzzle come not attached. Well, obviously (after you know how to solve the puzzle) the real challenge is to assemble the 2 pieces!
I do love the shape of the pieces and the very nice way both pieces come together.
I definitely advise it for anyone and I would even put it in my favourite from group 1 of cast puzzles along with cast loop.
