Weighing In at the End Alison Rosa Three-Fourths of an Ounce, a new line of condolence products including memorial candles and jewelry, is named after measurements taken by the early 1900s Massachusetts doctor Duncan MacDougall. After studying terminally ill people and euthanized dogs, he concluded that a body lost three-quarters of an ounce at the moment of death, so a soul must weigh that much. Scientists, however, have since discredited his methods and data. The designer Ted Muehling has contributed polished quartz ovals ($200 each) that weigh, yes, 0.75 ounces. His staff grinds the stones at a workshop behind his Manhattan boutique, on machines with wet sandpaper wheels that emit mournful sounds as they spin. Mr. Muehling, who was brought up Catholic, said the translucent stones remind him of his childhood image of the soul as an internal vapor that grows cloudier with every sin. The polished talismans are also ecumenically reminiscent of crystal orbs that Buddhist temple statues carry and pebbles that Jews place on gravestones. Information: 3-4oz.com.
