Buccellati's whimsical jam jars visually and physically capture the fruits of summer. Little works of art, they are individually handcrafted so no two pears or plums, oranges or lemons, are identical. Each sterling top, with naturalistically worked leaves and stem, and spoon (shaped like a branch with an attached leaf) displays the artistry of the Buccellati silversmiths, whose texturizing techniques produce a variety of light effects. The colorful Murano glass bases, made by the Seguso glassblowing family, are chased in white inside, adding to their luminosity. Each jar sells for $3,100 (except the pineapple, $3,400). At 46 E. 57th St., New York, 212-308-2900; and 9500 Wilshire Blvd., Beverly Hills, 310-276-7022.
