the engagement ring originally belonged to the late Princess Diana. it was given to Diana by Prince Charles for their engagement.
Her wedding ring
It's currently estimated at 4.2 million dollars U.S.D
The 28-year-old Prince used the dazzling oval blue 18-carat sapphire and diamond ring when he popped the question while they were on holiday in Kenya last month.
Because Jon and Kate are getting divorced. She doesn't want to wear it anymore. Maybe she is afraid she will lose it.
Before the Wedding, Prince William decided that he did not want to wear a wedding ring! He doesn't have to!!! However, Catherine's wedding band was made from traditional Welsh Gold like most royal brides.
$300,000
i think it is kept, because the welsh gold wedding ring was ordered by the Queen especially for Kate.
It is tradition that men in the Royal Family do not wear wedding rings.
In the 1950s, the average cost of a wedding was around $2,000-$3,000, which would be equivalent to roughly $20,000-$30,000 in today's money when adjusted for inflation. Keep in mind that wedding costs varied depending on location, size, and specific details.
