Some friends buy a beer for a friend's birthday, but Future's peeps drop around half a million bucks to get him dripping in diamonds.
The rapper was in Miami and hit up The Forge last weekend for a 34th bday celebration. We're told The Weeknd hooked him up with an icy "Low Life" pendant ... his manager, Ebonie Ward, gave him diamond-crusted dog tags -- and Young Scooter got him a BMFBG piece.
We're told all of the bling was commissioned by Avianne Jewelry in NYC. Elliot Avianne even threw in an awesome Pluto pendant. Bonus! Add in the 2 rings he scored from family members ... and Future's total haul was worth about $500k!!!
