What Makes Natural Fancy Diamonds Special? | BNT Diamonds

What makes natural fancy diamonds special?

Natural fancy diamonds are very exclusive and rare, even rarer than colourless diamonds. A true natural coloured diamond has been gifted to us by nature and can be found in a variety of colours, from pink to yellow to brown and even red. Fancy coloured diamonds are only found in a handful of places.

Only one in every 10,000 diamonds has a natural colour, which is why these diamonds are called fancy coloured diamonds. Fancy coloured diamonds are purchased almost exclusively for the intensity and distribution of the colour of the diamond. Criteria considered when purchasing a white or colourless diamond, such as cut proportions and clarity, are less important when purchasing a fancy coloured diamond.

Colour

Coloured diamonds come about due to various factors. For instance, yellow diamonds owe their cheerful hue to the presence of nitrogen. Blue diamonds owe their colour to the boron they contain. The cause of pink and red diamonds’ remarkable colour is not certain, although speculations state that they are the result of fractures in the crystal lattice. The rarer the colour and the more intensely the colour shows, the higher the value. Yellow and brown diamonds are most commonly found, while red, blue, and green diamonds are among the rarest of all fancy colours.

Intensity

Colour intensity, namely the deepness or richness of the colour, is the most important parameter when purchasing a fancy coloured diamond. The more intense the colour, the rarer and more valuable the diamond will be. Diamonds with lighter colour intensity levels such as faint, very light, light, fancy light, and fancy are more common than diamonds with richer intensities like fancy intense, fancy vivid, and fancy deep, and thus less valuable.

Carat

After colour grade, carat weight has the biggest impact on the price of fancy coloured diamonds. One carat equals 0.2 grams. The word "carat" comes from the carob seed, the original unit of measurement for diamond traders. The diamond’s price increases with every carat because they become rarer. Fewer than one in one million mined rough diamonds are large enough to produce a polished 1-carat diamond. The diamond prices for fancy coloured diamonds rise exponentially with carat weight.

Cut

Natural fancy diamonds are primarily cut to emphasise their colour. This contrasts with colourless diamonds, which are cut to maximise their sparkle or brilliance. While fancy coloured diamonds still exhibit brilliance, colour is the most important characteristic considered when they are being cut.

Shape

Shape refers to the overall outline of the diamond when viewed from the top (e.g. round, princess or cushion). A lot of fancy coloured diamonds are cut into non-common shapes to enhance their natural colour. Because of the rarity of fancy coloured diamonds, not all colours are available in all shapes at any given time.

De intensiteit of diepte van de diamant kleur is de belangrijkste parameter bij het aankopen van een gekleurde diamant. Hoe intenser de kleur, hoe zeldzamer en waardevoller de diamant zal zijn. Diamanten met een mindere kleurintensiteit zoals faint, very light, light, fancy light and fancy komen vaker voor dan diamanten met de rijkere intensiteit zoals fancy intense, fancy vivid en fancy deep. Deze laatste zijn dus waardevoller.

Clarity

As diamonds are formed deep within the earth under extreme heat and pressure, they often contain unique birthmarks, either internal (inclusions) or external (blemishes). Clarity grading goes from LC (loupe clean) or IF (internally flawless) to I3 (included). The higher the clarity scale, the more precious and special the diamond, and the higher the price.
Due to the nature of natural fancy diamonds, clarity is less important than it is in their colourless counterparts because inclusions tend to be masked by the diamond's colour.

Slijpkwaliteit

Gekleurde diamanten worden geslepen om hun kleur te benadrukken. Dit is in tegenstelling tot kleurloze diamanten, waarbij de schittering en glans worden benadrukt. Gekleurde diamanten vertonen ook een schittering, maar bij het slijpen zal steeds de intensiteit van de diamantkleur doorslaggevend zijn.

Vorm

De vorm verwijst naar de globale omtrek van de diamant wanneer deze van bovenaf wordt bekeken (bijv. rond, princess of cushion). Vaak worden fancy colour diamonds in ongebruikelijke vormen geslepen om hun natuurlijk kleur te versterken. Hierdoor zijn niet alle vormen in elke kleur op elk moment verkrijgbaar.
