Jay-Z splashed out £2.5million on Beyonce Knowles’ wedding ring.
Although the couple married in a secret ceremony in April, the 'Bootylicious’ singer had so far refused to show off the band until she was seen on a Miami beach with younger sister Solange last weekend.
The eye-catching piece is believed to be from celebrity jewellers Schwartz, a long-term favourite of the star. Mohammed Cimark, who runs Precious Gems and Jewels in London, confirmed the huge octagon-cut diamond was a rarity.

Lindsay Lohan wants to adopt a child.
The 'Mean Girls’ actress – who recently confirmed she is in a relationship with DJ Samantha Ronson – is looking forward to becoming a mother, and would like to help a child in need.
She said: 'At some point, I want to adopt a kid as well. A child in need or a newborn from another country, I’m not sure.'
Although the 22-year-old star – who has completed three stints in rehab for alcohol and drug problems – admits she is 'happy' in her relationship with Ronson, she stops short of crediting the DJ with helping her get her life back on track. Instead, Lindsay claims the positive changes in her are solely down to her desire to change.

Jay-Z was recently honoured at the UN Global Leadership Awards Gala in New York for his work bringing clean water to young people during a recent trip to Africa. He admits the trip had a huge affect on him as he got to see the problems in the country first hand, and it inspired him to continue his humanitarian work.

Jennifer, who previously revealed she fell pregnant as soon as she stopped trying to conceive, said: "I'd love to have more kids. I don't know when, we'll see, you know, that's the same way my first ones happened! We'll just do it the same way for the second time around!"

Geri said: "Jonathan Ross' wife wrote 'Stardust' and I thought, 'Oh wow, I'd like to do that.' "
The 36-year-old mother-of-one says the creative process of writing for film was really enjoyable.
