"Tall, with short-cropped hair and distinctive glasses, Peretti was both mercurial (she allegedly threw a fur coat into a fire when arguing with Halston) and minimal."

"'Take away, take away,' is how she described her process to Vogue in 1986.... Peretti led an ascetic, unhurried, and happy existence in Catalonia (perhaps somewhat akin to that of Georgia O’Keeffe in Taos, New Mexico), that she found conducive to creation. 'Of course, I’m slow,' she told Vogue. 'I have to crystallize a form, find the essence. It’s a continual training to be essential in your work, and then you have to be essential in your life, too.'"

From "Jewelry Designer Elsa Peretti Has Died" (Vogue). 

I've loved Elsa Peretti since the 1970s, and she is the only jewelry designer I've ever cared about.

Here's all the Elsa Peretti jewelry at the Tiffany website.
