This scene is very revealing because we can see the bracelet that Jacob gave Bella plus the bite mark left によって James and finally the ring, too.
Remember that this ring is very special because it belonged to Elizabeth Masen, the biological mother of Edward, so it has a lot of sentimental value.
The ring is gorgeous, with tons of diamonds. It shows the true 愛 that Edward has for Bella, and that he wants to spend eternity with her.
Of course, the ring scene in the book and movie is one of the most romantic and emotional of the Twilight series.
