Mont Blanc is the highest peak in Western Europe. It's also the name behind the iconic black lacquered fountain pen. To celebrate its 100th birthday, the Swiss company has added a new piece to its collection of wildly coveted limited-edition pens. At $173,000, there isn't exactly a popular demand for the Mountain Massif—only three were made. That, of course, was hardly the intention. Some 1,300 teeny-tiny diamonds were used to re-create an alpine silhouette along the white gold- and-transparent aqua glass casing; another 123 blue diamonds mimic the range's glaciers. And in place of Montblanc's familiar lacquered white star, a diamond cut in the shape of that emblem floats luxuriously in the cap. We wonder, would Dorothy Parker, equipped with such a pen, have complained that the labors of writing were so taxing that she had to lie down after writing a postcard?
