To my eyes, this stunning Juliska "Harriet" Globe Pendant Lamp ($750) looks like it's taken its inspiration straight from the sea. With its spiny protrusions and round body, it could be a cross between a beach-washed shell and a sea anemone. Though now, instead of hiding under the current, the shape has been reimagined for your home, to hang above a table or elegant foyer space.
Made by Juliska, this pendant has been mouthblown by Prague-area artisans using the same technique that's been passed down for generations, allowing the glass to be extremely thin. Each comes with a six-foot chrome chain and takes a 120-watt bulb (though I, of course, would suggest switching it out for a CFL).
