Angelina Jolie’s engagement ring took one year to be designed

Angelina Jolie was spotted wearing the ring on her wedding finger at the Chinese Art collection at the Los Angeles County Museum earlier this month, where she was pictured with Brad Pitt and their son Pax.

Brad Pitt, 48, designed the ring for the mother of his six children in collaboration with jeweller Robert Procop who broke the news of the engagement in a statement last Friday.

Robert Procop’s team said in a statement: “Brad had a specific vision for this ring, which he realized over a year-long collaboration with Robert.”

“He wanted every aspect of it to be perfect.”

Angelina Jolie, 36, and Brad Pitt confirmed their engagement last week in a statement – and their six children were said to be especially happy about the news.

Their spokeswoman said: “It is a promise for the future and their kids are very happy. There’s no date set at this time.”

Robert Procop said: “I was able to locate a diamond of the finest quality and cut it to an exact custom size and shape to suite Angelina’s hand. Brad was always heavily involved, overseeing every aspect of the creative design evolution.

“The side diamonds are specially cut to encircle her finger. Each diamond is of the highest gem quality.”

Experts estimate the ring cost around $250,000.

Angelina Jolie’s father Jon Voight was among the first to publicly congratulate the pair, telling Us Weekly: “I’m very happy for them.”

The actress has been married twice before – to British actor Jonny Lee Miller between 1996 and 1999 and then Billy Bob Thornton, from 2000 to 2003.
