How can I assess the carat weight of my diamond?

Carat: Diamonds are measured in terms of weight, not size. The chart below will give you a very good indication of their carat weight. The heavier the diamond, the greater the carat weight. Two diamonds of equal weight can have very different values because the quality is determined by the colour, clarity and cut. As diamonds increase in size, their cost tends to increase exponentially rather than arithmetically. Thus, a one carat diamond can cost significantly more than a half carat diamond of equal quality. The weight of a diamond less than one carat in size may also be described in terms of points. There are 100 points in one carat.

How do I assess the colour of my diamond?

Colour: While many diamonds appear colourless or white, they may actually have subtle yellow or brown tones that can be detected when comparing diamonds side by side. Colourless diamonds are the rarest and most valuable. Colour variations are a result of natural forces (temperature, pressure or trace elements) at work during their formation. Because subtle colour variations affect the value of a diamond, a colour grading scale is used to categorise the differences in diamonds. Diamonds are graded according to the GIA (Gemological Institute of America) colour chart.

How can I assess the clarity of my diamond?

Clarity is an indication of a diamond's purity and is determined by a diamond's naturally occurring internal characteristics. These are sometimes not visible to the naked eye and they are what make each diamond unique. The characteristics, or inclusions, may look like crystals, feathers, clouds or dark spots and the quantity, size, and location of these inclusions affects a diamond's value. Diamonds with fewer and smaller inclusions are generally more brilliant, assuming that the colour and cut are the same. The US Federal Trade Commission established the jewellery industry's standards for diamond clarity based on 10-power magnification. A diamond is graded by its departure from flawless - the complete absence of inclusions under 10x magnification. Less than 1% of diamonds have no inclusions and are called flawless (FL) or internally flawless (IF). VVS diamonds are also rare. VS diamonds are of superior quality and are used in fine jewellery. This clarity grade is more important as the diamond size increases. A large percentage of jewellery is made with SI quality diamonds. These are perfect for diamond studs or multi-stone diamond earrings, rings and bracelets or as accents in gemstone rings. I quality diamonds are acceptable as well for diamond jewellery or as accents but the sparkle is reduced by the number and location of inclusions.
