The four C’s

The best-known criteria for classifying a diamond are the four C’s. Carat, clarity, colour, and cut.

Carat is one of the four most important quality features – the so-called four C’s – that are used to determine the price of diamonds. It is a measuring unit for the weight of diamonds and other gemstones, with one carat equalling 0.2 grams. The heavier a diamond, the more expensive it is. However, keep in mind, that the price does not raise directly proportional to the weight in carats. Big diamonds are extremely rare and therefore a diamond of two carats costs more than double the price of one of one carat.

Ideally, a diamond is completely transparent and translucent – but in reality, most of the gems have impurities and are more or less cloudy. As a result, the desired sparkle is diminished. The so-called Inclusions may be embedded external minerals, tiny cracks, or growth-related crystal defects. The clarity scale ranges from the top categories FL (flawless) and IF (internally flawless) to VVS1 and VVS2 (very, very small inclusions), VS1 and VS2 (very small inclusions), SI1 and SI2 (small inclusions) up to I1, I2 and I3 (inclusions), where the impurities can even be seen with the naked eye.

Diamonds exist in a wide range of colours – they are available in yellow, red, green, blue, brown and black. However, the colourless to almost colourless gems are the vast majority. For them, the Gemological Institute of America has developed an internationally valid rating scale. It ranges from the top-quality colour D to the recognizable toned shade Z. In a somewhat coarser subdivision, the individual letters are grouped into six groups: very fine white (D and E), fine white (F and G), white (H), slightly tinted white (I and J), tinted white (K and L); the remaining levels to Z get the name tinted.

The cut is responsible for its brilliance and mesmerizing sparkle. In addition, one must know that the rainbow-colored brilliance of a diamond, its so-called fire, comes to its best with an optimal cut.

By nature, a diamond is colourless, but the varying degrees of refraction of the incident light rays create a variety of colours. However, if the cut is too pointed or too flat, this effect will be lost. Only with ideal proportion the light moves from facet to facet and is reflected to the viewers eye.

Care of diamonds

Diamonds are the hardest gemstones in the world and are very resistant to damage, but still a regular and correct care of these expensive gemstones is essential. To prevent damage, diamonds should not be worn during activities where they come in contact with cleaning agents or similar harmful substances. Clean your diamonds regularly to keep their original beauty for years after the purchase. Fingerprints and dirt can degrade the brilliance of the gems over time. Clean your diamonds with warm water, mild soap and a soft brush. Then rinse with water and dry with a lint-free cloth. In addition, we recommend to periodically subject diamonds to professional cleaning at a jeweller.
