What a rock! 

Amber Heard showed off her giant engagement ring on the red carpet with fiance Johnny Depp for the Texas Film Awards in Austin, Texas on Thursday.

Johnny stood by Amber's side for the night, where she was also honored with a trophy for the "Texas Film Hall of Fame." 

The cute couple looked picture perfect in their coordinated black getups. Amber sported a black netted dress, with fringe and flower accents and finished her look with red pumps, a bold lip and her hair swept back. 

Johnny matched his lady love, dressed in black from head-to-toe wearing a pea coat, button up, slacks and a newsies cap. 

The pair looked super in love as they laughed together and held hands throughout the festival ... but all eyes were definitely on the 27-year-old's huge sparkler! 

We can't wait to see these two walk down the aisle -- what do you think about Amber's ring?
