Pink diamonds are among the rarest jewels globally, with just a tiny number generated each year. These diamonds, whether they are gently coloured or vividly coloured, form wonderful jewellery stones. Most of these gems are discovered in Perth, namely the Argyle region, which yields tiny but brightly coloured pink diamonds. Other sources yield more giant stones that are less intensely coloured. However, they are still beautiful.
If you’re thinking about purchasing a pink diamond, keep reading to learn more about the grading and quality considerations that go into these stones. The purchasing factors for fancy coloured pink diamonds are vastly different from those for white diamonds.
Purchasing Fancy Colored Pink Diamonds in Perth and Understanding the Four Cs
The IGS coloured diamonds value listing includes pricing standards for irradiated pink diamonds, which may be found on the IGS website.
Colour: While the shape is the essential component in determining the value of colourless diamonds, colour is crucial in determining the value of fancy coloured diamonds. Hue, tone, and saturation are the three components of colour that make up a colour palette. Every pink diamond has a primary hue that is pink in colour. On the other hand, diamonds with pure pink colour are exceptionally uncommon and will fetch the highest prices of any pink diamonds in Perth available. (According to the colour wheel, pink is a light-toned red.) On the other hand, pink is recognised as a colour in diamonds by gemological labs.
There may be secondary colours such as brown, orange, yellow, and purple present in a pink diamond. Brown secondary colours, which are the most prevalent, have the lowest monetary worth. Attractive orange colours may provide a stunning contrast against rose gold. Those looking for a pink stone, on the other hand, may find purple secondary colours to be the most appealing.
Tone: A gem’s style indicates how bright or dark it seems to be. Very dark pink diamonds are more likely to exhibit brown solid secondary colours and be less saturated than lighter pink diamonds. Lighter pink tones may be gorgeous, while middle techniques can attain a more excellent saturation of colour than darker tones.
Saturation: Only a few pink diamonds have a high saturation level. On the other hand, gems with extremely low saturation may seem brown or grey.
What is it about colour that makes it “fancy”?
Colour is graded differently in colourful diamonds than it is in colourless or white diamonds. Colourless diamonds are rated based on their body colour, while coloured diamonds are graded based on the colour of their face-up, face-down face.
Pink diamonds may be pale, extremely light, or light in colour when paired with stones that are very light in tone. Darker tones might be fancy light, fancy, fancy intense, fancy vivid, fancy deep, or fancy dark, and they can be fancy deep or fancy dark. The most intense colours are found in the fancy bright grades. Fancy brilliant stones are the most costly pink diamonds because they are very uncommon and appealing.
The price difference between fancy light and fancy diamonds is enormous. Yet, fancy intense pink diamonds are just slightly more expensive per carat than fancy diamonds when compared to fancy diamonds.
Because each grade contains a spectrum of tones and saturations, it is essential to examine the diamond in its natural setting. Two fancy pink diamonds’ tone and saturation levels may be very different. The coloured diamond colour reference table illustrates samples of diamonds that fit into each of these classifications.
Clarity: While clarity has less influence on the price of pink diamonds than colour does, it may still make a difference. Inclusions are less noticeable in darker stones, and these uncommon gems are often not eye-clean due to the presence of inclusions. The better the purity of a light pink diamond, the more desired it is to own one.
Graining: Chemical impurities cause the colour of the majority of diamonds. On the other hand, Pink diamonds differ from most diamonds because their hue is caused by plastic deformation. This indicates that pressures on the crystal generate graining, which is responsible for the shade of these diamonds. Pink diamonds with tightly packed grains have a deeper tone and a more vivid hue than other pink diamonds. Some gems have an unpleasant hazy look due to zoning, referred to as texture in gemmology. Most significantly, if the zoning isn’t visible in the face-up diamond, graining will not affect the stone’s clarity grade.
