Floyd Mayweather: My New Ice Cost Seven Figures!

Floyd Mayweather really outdid himself this time ... dropping over $10 million on some new diamonds.

According to Floyd's rep, the giant ring alone is 50 carats and smaller necklace is made of 74 diamonds, each one being three carats each.

All told, Floyd's rep says the collection ran Floyd between $10-15 million.

Earlier this month, Floyd spent over a million bucks on a sick diamond watch while shopping in Dubai.
