Most jewelry shops will have a jeweler’s loupe on hand and will let you borrow it to inspect a stone you are thinking of purchasing. The jeweler’s loupe is one of those small eyepieces you see jeweler’s use to take a close-up look at a stone. Although you might not expect it, a real diamond will often have visible imperfections, such as small flecks of minerals or minor color changes. It’s actually the man made diamonds that will appear more perfect, since they are manufactured under carefully-controlled laboratory conditions. With diamonds, perfection usually means fake, but flawless diamonds do exist, so use the other tests on this list to help you reach a conclusion.
