Around the World: McDonald's Japan - New Jewelry Quarter Pounder Line

McDonald's Japan is set to offer a new, limited-time "Quarter Pounder Jewelry" line of three premium burgers later this month.

The very limited-edition burgers will each only be offered in limited quantities for only one day each on three separate Saturdays, starting July 6. They will feature premium ingredients like slab bacon and truffle sauce and come with names like "Gold Ring" and "Ruby Spark."

Here are the details:

On July 6, McDonald's Japan will serve the Gold Ring Quarter Pounder. It comes with a 1.5 cm-thick golden ring of grilled pineapple, 9 mm-thick, hardwood-smoked slab bacon, a "fruity" barbecue sauce featuring apple puree and pineapple juice, Monterey Jack cheese, and a 1/4-pound beef patty on a Kaiser bun.

On July 13, the Black Diamond Quarter Pounder will make its brief appearance and feature truffle sauce, grilled mushrooms and onions, Emmental cheese, and a 1/4-pound beef patty on a brioche bun.

Finally, on July 20, the Ruby Spark Quarter Pounder will be offered with five slices of chorizo sausage, grilled onions, a guacamole with lemon juice, garlic puree, and seasoned onions, an interestingly-ridged slice of pepper jack cheese, and a 1/4-pound beef patty on a soft French-style bun.

Each burger is priced at a premium 1000 yen (~$9.94 US) a la carte, or can be purchased in a "jewelry set" with medium fries and a drink for 1200 yen (~11.92 US).

To play up the theme, the Jewelry Quarter Pounders will come in a special box and bag.
