The owner has become ill and has chosen to sell the island at auction – unusually for a non-distressed luxury property -- as a means to monetize it quickly and efficiently.

"Unlike the traditional sales model, the auction model allows him to sell Innocence Island on his own timeline," said Laura Brady, the founder of Concierge Auctions, a New York-based luxury real estate auction firm charged with selling the island. The auction will take place on May 15 at the five-star Trump SoHo hotel in Manhattan. The property will sell to the highest bidder, at or above a $10 million reserve. Once sold at auction, Brady said the entire process will take about 60 days from start to finish.

Innocence is located in the Bahamas' Exuma chain of islands, home to the likes of actor Johnny Depp, magician David Copperfield and country music icon Tim McGraw. Exuma is the only part of the Bahamas where private islands regularly go on sale. "The Exuma islands offer privacy, seclusion and the most beautiful scenery the Bahamas has to offer," said George Damianos of Damianos Sotheby's International Realty, with which Concierge Auctions is working on the sale of the island. "Still, when we say that Innocence Island is 'one-of-a-kind', we mean quite literally that its size and splendor are unmatched."

One unusual feature is its 2,500-foot airstrip, which is one of the only in the Bahamas with its own pilot code. "Every time I descend upon Innocence Island, I relish hearing the pilot announce our approach by calling out the island's airport code, MYEY. I sit back, smile and await the privacy and relaxation to come," said its current owner in a news release. Read MoreYou're only a rich Brit if you've got $17 million
