Both of our family's know we plan on getting engaged soon. Recently his Grandmothere offered us her engagement ring that was also her mother's. I am deeply honored and surprised seeing as he has several other cousins/brothers. I've always dreamed of a platinum/white gold ring with a princess cut diamond. His grandmother's ring would be gold with a round cut. I'm torn on what to do. He is in favor of his family's ring and is leaving the ultimate decision up to me.... Any sugestions?
