It took almost two months, but Jennifer Aniston is finally showing off her giant engagement ring!

The former "Friends" star and fiance Justin Theroux were spotted in Santa Fe, New Mexico over the weekend -- where Jen debuted the massive rock.

Justin definitely did a good job with the sparkler, which features a BIG stone surrounded by diamonds.

Theroux popped the question to Aniston on his 41st birthday back in August, but the two have stayed out of sight ever since.

Jen was spotted wearing a ring on the set of her latest film, but it was just part of her costume.
