If a piece is 10 carat, the amount of gold is 41.7 percent gold, the remainder is other alloys. The 10-carat piece is harder and more durable, able to withstand daily wear. Higher carats are more suitable for occasional wear. Law requires each piece to be stamped with the percentage of gold, says Ed. If you're buying a diamond, the color, cut, clarity and number of carats determine the price, says Ed.
Word of mouth is the best way.
Ask your friends. They will know who they have dealt with and whether they were satisfied. A good diamond will sell itself. Ed pledges to help all customers with their jewelry purchases based on his knowledge and experience. Since he's his only employee and is not based on a high-overhead shopping district, he can often beat the high prices at other stores.
