Do your research in choosing a store. It is easy to use the internet and look up some statistics about the business. If they are an established business and have been around for years, they will proudly show this information on their website for every potential customer to see. When they are just starting up their business, they may not have access to much information about their goods.
Read the reviews other customers have posted. There are numerous third party companies which list reviews for every business out there today. These reviews are usually from real those who have purchased a product or service through that company and therefore are willing to share their own experience to better notify others of the kind of company they are dealing with. If someone posts a bad review, the jeweler is more likely to appropriate the problem and make the client happy again.
Ask your friends which jeweler they use. Feel free to publish on Facebook or ask your friends the very next time you see them. While you might not have seen these people in years, they may have substantial knowledge about a jewelry salesman because of a personal experience. They might also be able to provide ideas or discounts. You could be friends with the who owns the company and not have any idea! Your friends will always be completely honest about their experiences. No one likes to waste their money on a terrible product.

Wait to determine how the jeweler responds to the delay or problem. If they behave in a professional method, then you know you have found a good jeweler you can trust. This may take some time and, but the results is going to be satisfying when you know you can trust your jewelry with a specialist.
