Lafco House & Home Diffuser in Rosemary Eucalyptus, $95,

Diffusers are not such an improvement on the much-maligned potpourri: They smell good, but they clutter your environs and they
are precarious: Where the potpourri might have spilled everywhere, now the flimsy bottle, top-heavy with sticks, teeters on the edge of the coffee table, a fragranced disaster waiting to happen.

Not these handblown, hefty, venetian-glass diffusers, each the size of a small lamp. They’re design elements in and of themselves, with no labels, stickers or type, plus they come in about a million colors, each one in a different, amazing, sophisticated, subtle scent.
