Antonio Brown Goes on $500k Jewelry Shopping Spree

Antonio Brown Goes on $500k Jewelry Shopping Spree


's business is definitely still boomin' in the off-season ... 'cause the NFL superstar just copped an insane amount of jewelry worth HALF A MILLION DOLLARS!!

You already know the Steelers receiver LOVES ... but the dude keeps topping himself ... hittin' up his good friend Gabriel the Jeweler for the massive order:

-- Richard Mille watch ($190k value)

-- 2 more G.O.A.T. rings ($20k value each. Remember, he already had one)

-- 5-carat diamond earrings (50k value)

-- An insane diamond chain ($220k value).

Add all that up, and you have a haul worth a whoppin' $500k!!

No word on how much coin A.B. actually dropped ... but the dude's in a 4-year, $68 million contract ... so he can afford to do this a LOT if he wants.

Boomin', indeed.
