A week ago we speculated Robert Pattinson and Kristen Stewart could be breaking up, but now it appears things could be getting very serious between the Twilight co-stars - Rob gave Kristen a ring!

It's unclear whether the ring is that sort of ring. A friend told OK! Magazine, "The ring is rose-cut diamonds set in rose gold. It’s a very feminine piece of jewelry and very old." 

"The diamonds aren’t huge, and it doesn’t look like an engagement ring," the friend said. "Rob is more mature than Kristen and he’s ready to settle down."

Apparently the jewelry is worth about $17,000. So, is it a ring to take their relationship to the next level, or simply a very nice gift? We'll just have to wait and see...
