What to Look for When Buying a Loose Diamond

A universal standard for identifying diamonds has been set to allow consumers to know exactly what they are buying. The quality and value of a diamond is defined according to the 4 C’s.

Cut

This is the most important factor when choosing a diamond. The cut can define the beauty and fire of a diamond. The cut is the grading that determines how well the diamond sparkles. It covers brightness (the reflection of white light from the top surface), fire (flares of colour) and scintillation (flashes of light).

Cut grades range from Excellent, Very Good, Good, Fair and Poor. The grading takes into account attributes of the diamond that can only be observed and measured by highly experienced professionals.

Diamond cutting can be traced back to the middle ages; but it was much later than that when the importance of total symmetry to reflect light effectively was realised. It wasn’t until the 1900’s that the development of tools allowed for diamonds to be cut so well they had the radiance and sparkle we see today.

Nowadays, modern technology allows for the easier cutting of diamonds, but the old rules still apply. If cut too shallow the light reflects beneath; too deep and the light reflects sideways. The cut and shape of each diamond is based on its rough shape. The prime objective when cutting a diamond is always to achieve the best sparkle or brilliance and the maximum size of diamond from the rough.

Colour

When buying a loose diamond, the perfect diamond actually has no colour at all. The colour of a diamond is graded D to Z with D being completely colourless and Z having a yellow tinge. Many of the differences in colour are invisible to the untrained eye but can make a huge impact on quality and price. Always buy loose diamonds from a source you trust.

Whilst the majority of diamonds are colourless, natural diamonds can be found in almost every colour. Pinks, yellows and blacks are quite widely used in jewellery making. Some colours, such as a natural deep red, are very rare and can command huge prices.

The discovery of diamonds in Australia in the 1970’s brought to the market a number of strong colours. Particularly yellow and a deep brown which is called ‘Champagne’. Pink diamonds also from the Argyle mine in Australia fetch a premium and are very attractive. Very intensely blue diamonds are also found, but again are very rare. In the case of these ‘Fancy Colour’ diamonds it is the intensity of the colour that sets the value.

Clarity

When choosing a loose diamond for sale, you need to consider its clarity. Clarity refers to the absence of inclusions and blemishes. Diamonds with the least and smallest inclusions achieve the highest clarity grades. These are classed as Flawless and are incredibly rare and command higher prices.

So what exactly are inclusions? Due to diamonds being naturally occurring, the diamonds will have internal characteristics indicative of growth. These may be small particles of other minerals trapped within the diamond or irregularities within the actual structure of the diamond.

The clarity of a diamond depends upon a subjective judgement made by and industry professional against an agreed industry standard. However, it is very difficult to assign a grade as no two diamonds are the same.

The majority of loose diamonds for sale will have some kind of inclusions which is almost impossible to see with the naked eye. Inclusions should not be classed as a fault as they are a work of nature and cannot be avoided.

Carat

The final C to consider when choosing a loose diamond for sale is carat. This refers to the weight of the diamond and not its overall size. The cut of the diamond has a direct correlation to its carat weight.

The majority of diamonds are considerably smaller than a carat in weight, diamonds bigger than this are rare and cost a lot more. It is estimated fewer than one in one million rough diamonds are large enough to produce a finished one carat diamond.

The cut of a diamond can affect its carat weight quite dramatically. You can get diamonds that when looking at them from above seem to be the same size, but if they have not been cut correctly taking into account proportions, there will be large differences in actual carat weight.

A diamond with incorrect proportions may look bigger but this does not mean it has a higher monetary value. As previously mentioned when discussing the cut of a diamond, one with incorrect properties will not reflect light properly and this will affect the cut properties. So just because it is larger in carat weight if the cut isn’t good quality it will be worth less in value.

Diamonds
  • Round Brilliant

    The round brilliant cut diamond is the most popular, its shape generally makes it more superior to other cuts with more brilliance and fire.

  • Oval

    The oval cut diamond has a similar brilliance and fire as the round cut but creates the illusion of greater size because of their elongated shape. It is a popular cut that has a classic appearance with a modern twist.

  • Marquis

    A marquis cut diamond has a dramatically beautiful appearance. It’s shape makes it more suite to those with long, slender fingers. It’s cut can create the illusion of a great size than it actually is.

  • Pear

    The pear shaped diamond combines the exquisite features of the both round and marquis cut diamonds. A pear shaped diamond should be very symmetrical and is cut to maximise its brilliance.

  • Heart

    The heart cut diamond is on of the most demanding cuts to create. It is perfect for engagement or anniversary rings as it is an unmistakable symbol of love. It’s detail is reflected best in stones over 0.50ct.
