Price of Diamonds

 

What Influences The price of Diamonds?

Diamonds are cut in a range of shapes, sizes and qualities all of which influence the price. Diamonds that have an excellent or very good cut grade will reflect maximum fire, brilliance and sparkle and they will be higher in price than diamonds with a good cut grade.

The shape of Diamonds

Round Brilliant Cut Diamonds are the most popular shape of diamond for engagement rings followed by the Princess Cut. Any diamond that is not Round in shape is known as a Fancy Shape Diamond. Asscher, Cushion, Emerald, Heart, Marquise, Oval, Pear,  鑽石手鏈 Princess, Radiant and Trilliant cut diamonds are all fancy shape diamonds. Round Brilliant Cut Diamonds are the most expensive mainly because when cutting a Round Brilliant Cut diamond there is a greater loss in rough which has to be factored into the price. Another reason why Round Brilliant Cut diamonds are priced higher is because they take longer to polish and cut than other diamond shapes and the demand for Round Brilliant Cut diamonds is greater than all the other diamond shapes.

Clarity Influences Diamond Prices The most

The clarity grade of a diamond influences the price obtained more than any of the other factors. Diamonds that have high clarity grades of VVS1 or VVS2 have extremely hard to find inclusions even with a jewellers 10x loupe. These diamonds are almost pure and rarer to find than diamonds with lower clarity grades such as SI1 or SI2 and therefore command a much higher price. The rarest of diamonds have an Internally Flawless -IF or Loupe Clean clarity grade and these diamonds fetch premium prices.

Colour Influences Diamond Prices

Colour is another important factor that influences the price of a diamond. Diamonds are graded for their colour alphabetically starting at D colour going down to Z colour. Diamonds that are colourless or show the least amount of colour obtain the highest prices along with fancy coloured diamonds such as pink, red, green and blue diamonds. Diamonds that display the least amount of colour are known as exceptional white. Exceptional white diamonds includes D and E colour graded diamonds. Rare white is the next colour grade and this includes F and G colour diamonds. H colour diamonds are graded as white and I and J colour diamonds are known as slightly tinted white diamonds.

Cut Influences Sparkle, Shine & The price of Diamonds

Did you know that if the diamond is poorly cut, the colour and clarity can not make up for it? The cut of a diamond is what makes a rough diamond sparkle and shine. If a diamond is poorly cut, the light that enters the diamond from above will leak out of the sides and bottom of the stone, and the diamond will not have the optimum amount of sparkle or fire-regardless of its colour or clarity. Excellent and Ideal Cut Diamonds have been cut to precise standards to display the beauty of the diamond.

Excellent and Ideal Cut Diamonds have perfection in proportion, symmetry and polish and they will always display the maximum brilliance, fire & scintillation. Excellent and Ideal Cut Diamonds have properly proportioned facets, excellent symmetry & polish. Since 97. 5% of a diamond’s brilliance is controlled by the quality of the cut Excellent and Ideal cut diamonds obtain higher prices.

The Diamond Cut Grade is made up of three main controlling factors – Proportion, Symmetry and Polish. The light return of the diamond more commonly known as sparkle or brilliance is also an important factor but it is governed by the proportions and symmetry of the diamond cut. Diamonds with a very good cut grade reflect most of the light that enters them, dispersing a good deal of brilliance. Very good cut diamonds have proportions which often overlap and are comparable to Excellent cuts but just differ slightly in one area or measurement. Very good cut diamonds are also highly valued.
