The Malmaison Classique Flatware set made by Christofle is as close to dining perfection as you can get without carving eating implements directly from precious gems. The collection includes knives, forks and spoons made of sterling silver (knife blades are stainless steel) and trimmed in diamonds of exceptional quality. Each one of the diamonds is hand set in France, so it takes several months to complete each flatware set. Price: $18,600, which includes one of each: dinner fork, dinner knife, soup spoon, salad fork, and teaspoon. To make a table setting for eight diners, you'll need $148,800.
