Online retailers selling jewelry understand this problem and they usually offer a phone number where you can talk to an experienced salesperson and get an answer to all your queries. Therefore, you should only buy jewelry from an online store that allows you to call a customer service number and speak to a salesperson in order to get an answer to all your queries.
Before you click the buy button to buy that diamond jewelry piece, you need to carefully read the return policy of the store. Several sites claim to offer a 30-day return policy but in most cases, you have to pay a restocking fee. Also, they might not accept the return in case they don’t want to. Usually, these things are mentioned in fine print in their return policy.
