Puzzle, The Diamond
date: label: Date made
content: 1981
notes: label: Description
content: This object is named The Diamond but other photographs of what appear to be the same puzzle show packaging labeled Dream Puzzler and Wonderful Puzzler.
label: Description
content: The Diamond is in the shape of a cuboctahedron, a fourteen sided solid figure formed from a cube by slicing off each corner along the lines that connect the midpoints of the edges of the cube that meet at the corner. A cuboctahedron is a special case of a truncated cube (see puzzle 2006.0061.13). In its solved position, The Diamond has six square faces where the truncated cube puzzle has six octagonal faces.
label: Description
content: The square faces of the cuboctahedron are colored the same as a traditional Rubik's cube, yellow, orange, green, red, blue and white. The eight remaining faces are equilateral triangles that are colored using two different shades of pink, two different shades of purple, gold, silver, turquoise, and light green.
label: Description
content: Unlike the Rubik’s Cube, whose six square faces are made up of nine small squares, the nine shapes that make up the square faces of The Diamond include one small square, four pentagons, and four very small right triangles. The eight triangular faces of The Diamond is made up of three equilateral triangles and one hexagon. It uses the same mechanism as the Rubik’s Cube to rotate the square faces
label: Description
