HELP! I know nothing about the subject of rings and such. I''m getting married and would like to get a personalized ring for my soon to be hubby. I found a great white gold band it''s 6.5mm. I would like to add something on this simple ring and was wondering if it''s possible to engrave on white gold. It would only be about 4 letters. Please! I need to get something soon! HELP!
