Exercise your grey cells with stuff made of precious stones and watch out for some dazzling results! Try putting the same colors or shall I say gems together on this jeweled Rubik’s Cube. Designed by Fred Cuellar, this exclusive brain-toy was made to commemorate the 15th Anniversary of the Rubik’s Cube. This full-size, fully working cube is covered with 185 carats of precious gems, 1.5 pounds of pure sliver with eight coats of hand-painted enamel.
Only 2,500 of them were made for $10,000 and each carried a Signed Certificate of Authenticity with Erno Rubiks signature on it.
