The Donald has arranged a deal with the tony Graff diamond sellers (search), in which the company will provide a 13-carat masterpiece ring in return for the November appearance of the jeweler's products on "The Apprentice," (search) a source close to Trump said Tuesday.
In addition, Trump's sexy model fiancee has agreed to pose in ads for the tony, high-end gem seller as part of the overall bling-bling-for-shilling deal, the source said.
The bodacious bauble, which will be put on Melania's finger during the couple's wedding ceremony in January at Mar-a-Lago in Palm Beach, is studded with 15 perfect emerald-cut diamonds in a platinum setting.
A Graff spokesman was not available to say exactly how much it was worth, but the Trump source said it is worth as much as $1.5 million.
Jewelry experts told The Post a ring the size of the Trump ring usually goes for about $500,000 -- but because it comes from Graff, it could be worth much, much more.
"You would be buying the name for something like that," said one jeweler.
Graff made its big appearance on a Nov. 11 episode of the show. The team that won that week's test of business acumen earned a $50,000 shopping spree at the diamond seller's New York location.
Graff is also the company that supplied the $2 million engagement ring that Trump, 57, presented to his soon-to-be third wife sometime in April of this year.
Spokespeople for both Trump and "The Apprentice" did not return repeated calls for comment last night.
The ring arrangement isn't the first time a Trump male has mixed finance and romance.
Trump's 26-year-old son, Donald Jr. worked out as similar deal with the Bailey Banks & Biddle jewelry store in New Jersey's Short Hills Mall.
A source said that the real estate scion agreed to promote the gem store in return for the $100,000 engagement ring he presented fiancee Vanessa Haydon last month.
He presented the ring in a ceremony at the store -- with the media in tow. Nether Trump nor the Jersey jeweler would talk about what was exchanged for the ring at the time.
The year 2004 has become the year in which love and largess combined in the world of Celebritydom like never before.
The height of the of the freebee free-for-all came at last month's coupling of "The View" host Star Jones and hubby Al Reynolds, in which the bride chose wedding "sponsors" such as Continental Airlines and got a slew of freebees from wedding suppliers.
