Evaluate brilliant quality
If you want to buy brilliants, it is important that you can determine the quality of your investment or brilliant jewelry. This succeeds if you know which aspects you should pay attention to. The most common classification takes place according to the so-called 4Cs, which we explain in detail in our guide. In addition, there are other important criteria, such as the fifth C, the indispensable certificate, as well as, for example, the indicators cut finish in brilliants, symmetry, polish and fluorescence. Also, investment brilliants should always be untreated. Here it quickly becomes clear: A brilliant as an investment must necessarily meet other criteria than a pure jewelry stone.
Carat – Weight
Brilliants. A metric carat weighs exactly 0.2 grams. This unit of measurement should not be confused with the carat, which is used to measure gold content. The more carats a brilliant has, the higher its value compared to brilliants of the same valuation. However, it should be noted that the price of the gemstone does not increase proportionally with its weight, but exponentially. A two-carat brilliant, for example, is worth more than two one-carat brilliants of the same grade because of its rarity. How many carats you should bet on depends on various factors, we will be happy to advise you personally.
Clarity – Purity
Most brilliants have inclusions, small features that occur naturally. The smaller these are, the better the brilliant can reflect incident light and the purer it appears. Flawless brilliants are classified as flawless and have a very high value because no inclusions can be seen in these gemstones, even when magnified ten times by trained gemologists.
Color
Brilliants are usually colorless or nearly colorless and are especially valued when they appear without any tint. These completely colorless Brilliants are very rare and only they can refract incident light throughout the color spectrum. The color of a brilliant is determined by an internationally accepted grading scale. Brilliants in the colors D (high fine white+) to G (fine white) are particularly valuable, except for rarities in intense natural colors. These colorings are caused by inclusions in the stone, such as silicon or nitrogen, and range from transparent blue-white to dark brown.
Cut
Each cut changes a brilliant and its value. This refinement is about producing the best brilliance and color decomposition. Ideal as an investment brilliant is the brilliant cut, as it best brings out the fire of the brilliant, that is, the refraction of the incident white light into its spectral colors. It also gives the most detailed criteria for determining its quality. Other cuts include princess or marquise. The quality of this brilliant cut is rated from poor to excellent. Also measured on this scale is the symmetry of the cut, as well as the polishing that is done to complete the processing.
