Diamond

Diamonds are among the most valuable and rare products of the natural world.

The price of a cut diamond is determined by the combination of four factors, the so-called “4 Cs”

Carat

The CARAT of a diamond is a measurement of the diamond’s WEIGHT. A carat represents a weight of 0.2 grams. The smallest cut diamonds have a weight of 0.005 carats and a diameter of one millimetre. A one carat diamond tends to have a diameter of 6.5mm. The rule of thumb is, the larger the diamond, the higher the price. Nevertheless there are also other factors which play an important role, as we will go on to explain.

Carat

Clarity

The CLARITY indicates to what extent inclusions are visible in the diamond. These are areas of the diamond which have not become totally transparent during its creation over millions of years, which remain visible within the cut stone. One determines the clarity according to the size, number and position of the inclusions. The fewer, smaller and more marginal the inclusions are, the more valuable the diamond is. A diamond can be denoted as flawless, when an expert viewing the diamond enlarged 10-fold can not identify any inclusions. Diamonds with larger inclusions are also called piqué diamonds. With these gemstones one can see the flaws with the naked eye. Rivoir Diamonds contain no inclusions visible to the naked eye.

Clarity

Colour

The COLOUR of a diamond can range from so-called full colourlessness to a bluish white, to a light to medium yellow and brown tones. Coloured hues which go beyond this scale are so-called “fancy colours”, and so rare that the value of these coloured stones can not be estimated. The whiter a stone is, the more valuable it is. Only extremely rare fancy colours are more valuable. The colour “G” of a diamond is called fine white. Colourless or very fine white+ diamonds are denoted with the letter name “D”.

Cut

The CUT plays a very important role in the overall impression and beauty of a diamond. The knowledge of how to perfectly cut and polish a diamond in order to bring out its brilliance to the greatest possible extent has only been perfected in the last 100 years. The cut is determined according to three factors: the proportions of a stone denote its ability to reflect light. The more light reflected (the so-called “light output”), the more a diamond sparkles. The quality of polish determines how well the stone was cut and how flawlessly its surface was finished. The symmetry demonstrates how perfectly the individual facets of the diamond sit together, and how good its proportions look. The so-called “fire” of a diamond often corresponds to its cut. The round brilliant cut is one of the most popular diamond shapes.

Confidence

There is one criterion which is particularly important to us which we would like to add to the 4 C’s described above: “TRUST”. As a member of the Responsible Jewellery Council (RJC), Rivoir offers transparency when purchasing diamonds, and is aware of its responsibility as a modern jewellery manufacturer. We exclusively use diamonds from ethical sources and pay attention to fair working conditions in the extraction process. Additionally we offer our customers ways to comprehend the path each of our Canadian diamonds travels. Through a laser engraving in the girdle (centre of the stone), the Canadian diamonds can be traced back to the mine, and are certified by an independent gemology institute.
