How to assess the carat weight of your Diamond?

Carat: Diamonds are measured in terms of weight, not size but the chart below will give you a very good indication. The heavier the diamond, the greater the carat weight. Two diamonds of equal weight can have very different values, because the quality is still 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 one-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 1 carat.

How to assess the colour of your 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 of all. Colour variations are a result of the natural forces (i.e., temperature, pressure, trace elements) at work during the formation of diamonds within the Earth. Because subtle colour variations dramatically affect the value of a diamond, a colour grading scale is used to categorise the shading differences from one diamond to the next. Diamonds are graded according to the GIA (Gemological Institute of America) colour chart.

How to assess the clarity of your diamond?

Clarity: is an indication of a diamond's purity. Clarity is determined by a diamond's naturally occurring internal characteristics. These characteristics 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 does have an affect on a diamond's value. Diamonds with fewer and smaller inclusions generally are more brilliant, assuming that the colour and cut are the same.

The U.S. Federal Trade Commission has established the jewellery industry's standards for diamond clarity based on 10-power magnification. A diamond is graded by its relative departure from "flawless"--the complete absence of inclusions under 10 x magnification. Less than 1% of all diamonds ever found have had no inclusions and can be called flawless (FL) or internally flawless (IF). VVS diamonds are also extremely rare. VS diamonds are of superior quality and are used in extremely fine jewellery. This clarity grade becomes more important as the diamond size increases. A large percentage of jewellery is made with SI quality diamonds. These diamonds 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.
