Angelina Jolie auctioned off jewelry to raise money for her non-profit, Education Partnership for Children in Conflict.
A vintage Robert Procop choker and a cushion-shaped emerald ring co-designed by Jolie will come under the hammer at Tiancheng's Jewelry and Jadeite Spring Auction on June 15.
The actress wore the choker in the film "The Tourist" and it's expected to fetch up to $770,000 U.S. dollars. The second piece from "The Style of Jolie Collection" made its debut at the Kung Fu Panda 2 premiere in 2011 and is valued at $200,000.
Proceeds from the sale will be donated to the Education Partnership for Children in Conflict, a non-profit group founded by Jolie.
The organization is committed to placing out-of-school children back in class and improving the learning environment of children affected by wars.
