Price of diamonds – What is the most expensive diamond?
Luxury has always been a word closely associated with diamonds, but despite their almost always lavish appearance, prices for individual stones can vary quite widely. Diamond prices will depend on the ‘Four Cs’ of Cut, Clarity, Colour, and Carat Weight which will need to be taken into account to understand a diamond’s price, the most expensive diamond ring will score highly in all four.
Understanding the 4 C’s
Cut – A diamond’s cut is different from its shape. The cut will determine how the diamond sparkles. A well-cut diamond will allow light to travel through the stone and bounce back to the eye for a truly dazzling effect. The Round Brilliant, for example, is the most popular cut and will cost more than Oval or Marquise cuts.
Clarity – A diamond’s clarity refers to any blemishes within the diamond. This can usually only be visible to a diamond expert, who magnifies the diamond in order to view inclusions or blemishes. The most expensive diamonds in the world will be nearly flaw-free.
Colour – Colour is another major factor in determining diamond price. Diamond colours are ranked from D to Z. The rarest, and most expensive rating is D which would be a fully colourless stone. Diamonds rated with a J start to exhibit a slight tint, which becomes more prominent all the way down to the lowest Z rating.
Carat Weight – The fourth and final ‘C’ is carat weight. The heftier the weight of a diamond, the higher the carat will be. You can expect the diamond’s price to increase exponentially along with carat sizes. A 1 carat diamond price will be far higher than a 0.5ct diamond price. And ‘magic weights’ like 1ct or 1.5ct will be significantly more than carats just below these thresholds.
What is the Most Expensive Diamond?
Diamond prices will depend on the 4 C’s mentioned above. Be sure that your diamond receives marks in terms of quality which match its price tag, these should be outlined in its certification. There are roughly 14,000 different grades used by the diamond industry in order to rate a diamond’s quality and price. What may seem a tiny difference in colour or clarity to the untrained eye could drastically impact the value of a diamond. The difference between a D or F colour grade diamond, for example, will be almost indistinguishable to most but under close magnification these are the differences which ultimately dictate diamond value.
