The color of a diamond depends on impurities and defects in its structure, natural radiation exposure. The color may be uneven - spots or patches.
Perfectly clear diamonds are extremely rare. Most often, small foreign crystals or microcracks can be found in their structure.
When evaluating the value of a diamond, its weight plays a major role, especially if the stone is small. All over the world, the weight of diamonds is measured in carats, abbreviated ct (1 carat = 0.2 grams).
To determine the value of a diamond, you need to study its basic characteristics (color, clarity, faceting, and weight) and the current price of one carat.
When faceting, a diamond loses 40-60% of its own weight. During processing, the jeweler covers the stone with numerous flat surfaces - facets.
A diamond certificate is a document thanks to which you can be sure that you are buying a real stone and its price is justified.
