Diamonds are not only exciting and versatile, but also valuable collectibles. A good investment diamond should be over 1 carat, and of the best color and highest clarity. The quality must always be confirmed by an independent laboratory. The most prestigious laboratory is the GIA (Gemological Institute of America), but also the diamond testing laboratory in Idar-Oberstein has an international reputation. Expert opinions of these laboratories are not only meaningful in terms of color, clarity and weight of diamonds, but also evaluate the proportions, polish and symmetry. Since proportions are responsible for light reflection, certain requirements must be met. Otherwise, the diamonds look dull and lifeless. Of the best quality, they can experience significant price increases over the years.
