Grand constructions for Iamond Ring


In 2017, John Greening, one of the world's outstanding puzzle aficionados, custom-ordered our Iamond Ring and Octiamond Ring in special colors and sizes 6. 7, and 8.

Some years before, Jacques Ferroul in France sent us these beautiful variants of the Octiamond Ring surrounding a core of hexiamonds:
