The first thing you need to do is find an online jewelry store that you can trust. You will have to do a little bit of detective work in order to eliminate the less desirable companies and end up with a list of jewelers that you feel confident doing business with.Find out if the website is secure. The jeweler's website should have 128bit SSL security. This is an absolute must when you are purchasing online, since you will most likely be using a credit card or supplying your bank account information. Somewhere along the line you will be supplying information about yourself, and the 128bit SSL security will ensure that no unauthorized party can get access to your information.
