French Iced Iggy Azalea Up For $100k!!

French Montana threw down stacks to bling out Iggy Azalea's digits ... TMZ has learned.

Sources close to French tell us the rapper dropped about $100k on the 7 rings he gifted her earlier this week. The rings were crafted by celeb jeweler Iceman Nick, who's also done some expensive bedazzling for a bunch of other rappers.

The purchase did the trick. Iggy gave French a shout-out on Instagram, after weeks of denying they've hooked up.
