Do Christians wear jewelry on their wedding? If yes, what kind of jewelry?

For the Christian that's neither here nor there. Read Romans 14 as it is the same principle.

We do. Whatever can be acceptable. I suggest you not wear something overly exaggerated. Choose jewelry that fits your wedding dress perfectly. I wore pearls and water drills at the wedding. And I was wearing my engagement ring, waiting for the wedding bands' exchange, and my engagement ring is a heart-cut diamond band in platinum from DarryRing, so it would be weird if I wore something yellow gold. I chose head yarn with water drills, a pearl necklace, and pearl earrings. And they matched perfectly. Well, if you're not sure what to wear, choose less. If you're in the denomination of Christian that doesn't wear Jews, talk to your pastor to confirm that!
