Do Your Homework.
To negotiate effectively, you need to be knowledgeable about diamonds. This doesn’t mean that you need to attend classes, just brush up on the four C’s of diamonds. Understanding cut, color, carat, and clarity will keep you from purchasing a poor quality diamond.
Before you are ready to make the big purchase, go to several jewelry stores and check out their prices. Know what kind of diamond you want, following the four C’s, and check out the average prices on them. Knowing the prices that other stores are charging will keep you away from jewelers that are overpriced. A good place to start shopping for prices would be with some of the more reputable online retailers. Check out www.BlueNile.com and http://www.adiamor.com. Also, one of the best kept secrets for great deals on engagement rings is Sam’s Club and Costco. Believe it or not, these large retailers have such huge buying power, that they often sell rings just above wholesale prices. You can also checkout Ebay for a huge selection and great pricing on engagement rings. Many of the sellers are large New York City jewelers offering better deals than you’ll find in their stores.
