The rings are massive with plenty of, yes, bling. The Miami Heat were presented their Championship rings prior to tipping off the season against the Boston Celtics. The Rings are 14-karat yellow gold and have 219 diamonds, totaling 10.8 carats each. It weighs over 114-grams, so heavy in fact, if you wear it, you would indeed walk with a limp. The Championship jewelry is designed by Minnesota-based design leader Jostens, with 115 year tradition of making championship jewelry and hardware.
