Why does a wedding ring have to have a diamond?
A diamond is the stongest and hardest gemstone. You will be wearing this ring nearly all the time for the rest of your life. I would think long and hard about getting another gem for this very reason. Some gems like Emeralds and opals are very very fragile and need specialist care to maintain their colour. In addition, be careful about which setting you choose, some modern ones though beautiful, are more prone to breaking if they are knocked. Claw settings (4 or more), and rub-over settings are the safest.
