Von Miller's Custom Super Bowl MVP Ring ... Drops $25k

Von Miller continued his baller diamond binge ... this time, dropping $25k on an iced out custom Super Bowl MVP ring, complete with 15 carats in diamonds!

It was all part of a $120k shopping spree at the exclusive Avianne & Co. in NYC -- where the Denver Broncos superstar also scooped up a diamond tennis chain and a fancy cross pendant.

But the ring ... damn.

We're told it's comprised of 14 karat rose gold and covered with VS quality diamonds.

The top has the letters MBG -- which we're told stands for Money Bag Gang (Von's crew of close friends).

The side has an image of Texas -- Von's home state.

Von's reportedly expecting to sign a $100 million contract this offseason -- so, why not treat yo'self, right??
