Yes, Christians wear jewelry on their wedding. They wear religious jewelry like cross jewelry. As cross is a symbol or a reminder of Christ’s sacrifice for them. The cross reminds that it is empty, Jesus is risen, and He is alive! some Christians believe that wearing a piece of religious jewelry can be an excellent opportunity to share your faith and act as an expression that you are proud to be a follower of Christ. Some days before I bought a silver cross necklace from Jewelry1000.com,which I like very much. Thanks a lot.
