Inside Joan Rivers' Private Collection of Jewelry, Clothes and More

— -- Joan Rivers said she viewed jewelry as art and now her baubles are up for sale, along with her lavish collection of designer gowns, home furnishings and other personal belongings.

The late comedienne’s private collection will be auctioned at Christie’s in New York City. Nearly 300 lots are for sale, ranging from a Tiffany dog bowl, to the desk and chair where she may have written her jokes, to an Edouard Vuillard painting that may fetch more than $120,000.

“There’s really just incredible depth to her collections,” Gemma Sudlow, Christie’s specialist head of Private & Iconic Collections, told ABC News. "There’s glitz. There’s glam. There’s that Hollywood feel to it, that show business feel to everything."

The home furnishings come from Rivers’ 11-room, three-story penthouse apartment on Manhattan’s Upper East Side. The apartment, which Rivers had lived in since the late 1980s, sold for nearly $30 million last July.

Now, nearly two years after Rivers’ unexpected death at age 81, her daughter, Melissa Rivers, is parting with her mom’s items.

Rivers’ collection of couture clothes and jewelry is currently being sold in an online auction. More than 200 lots of her other personal belongings will be sold at a live auction at Christie’s on June 22.

The collection is on view and is free and open to the public at Christie’s through June 21. Items range in price from $400 to well over $100,000.

A portion of the auction's proceeds will go to two of Rivers' favorite charities, the New York City-based God's Love We Deliver and Guide Dogs for the Blind in San Rafael, California.
