Finding a good jewelry store to buy a good engagement ring

After you've made an overture of marriage with your girlfriend, it's time to find good jewelry stores to buy an engagement ring. The jeweler is sometimes just as important as the jewelry. 
If you have no idea about jewelry stores at all, you should get references from your friend or your workmate. They'll be more honest than an advertisement and they can tell you where they bought jewelry from and their experiences on buying engagement.
After you have known some good jewelry stores with friend’s advice, you should make sure employees are professionally trained. Look for certificates that show that the staff has been trained by an industry recognized association or organization.
Find a jewelry store providing repairing jewelry service. You must want someone who knows how to handle jewelry when you meet jewelry broken.
