As for the rock, a source tells Life & Style that “it’s a huge emerald-cut diamond. It’s a rectangle with tapered diamond baguettes on the sides. It’s beautiful.”

The source estimates the diamond to be about eight carats.

“Just after Jen got engaged, she called all her friends and told them about it,” the friend reveals. “She was so happy and said she loves the ring. I think she was overwhelmed and overjoyed by the size and beauty of it!”
