Everyone knows that celebrities love to go over the top. And why shouldn’t they? With millions of dollars in their bank accounts, engagement rings for the stars can’t be cheap. Curious about some of the past splurges of some of Hollywood’s big stars? Over the years, Hollywood has seen some stones that have only matched it’s wearers in star potential.

When Richard Burton proposed to Elizabeth Taylor, he sought the advice of many of the world’s top jewelers to come up with a lavish ring. Burton eventually settled on a 70-carat pear shaped diamond engagement ring that, by today’s standard may be a bit modest, but which back in the sixties was considered highly extravagant.

Tom Cruise presented Katie Holmes with a wedding in a candlelit Italian castle. The wedding ring Tom chose for her reflected a five carat oval diamond in platinum and pave settings. Meanwhile Scarlett Johansson also chose a pave setting band when she became engaged. Her engagement ring featured a three carat round diamond.

Celebrity engagement rings typically go for a sum of around $100,000, on the low end of the spectrum. Some of the more extravagant spenders will pay up to a few million dollars for their wedding rings.

Other celebrity diamond ring highlights include Ashlee Simpson’s ring, which is a 4-carat Asscher cut encircled with several smaller diamonds. An Asscher cut is a unique cut that is quite rare today. Fergie’s ring, on the other hand, was a three-carat round brilliant cut diamond in a platinum band.

But perhaps Eva Longoria’s ring is one of the highlights of celebrity engagement rings. When Longoria married Tony Parker the two exchanged nearly identical engagement rings except that his did not feature stones. The two wed romantically in a highly publicized wedding in Paris in 2007. Longoria wore a white gold band that included double rows of eighty brilliant cut diamonds, separated by a row of twenty-seven square cut diamonds.
