Diamond Quality
Any diamonds of good quality will be an expensive purchase. Taking the time and effort to undertake some internet research (as you are now doing) before purchasing diamonds will pay dividends. To assess a diamond's quality it is important to find out as much as you can about the so-called 4 C 's before purchasing a piece of diamond jewelry. The 4C 's  provide a good guide to quality - they consist of:

  • Carat Weight
  • Cut Clarity Color & Fluorescence

Although the 4C's is the term which is commonly used we would include another quality factor...

  • The Cost

The Cost and the Quality
One month's salary is a good guide to the cost of a diamond engagement ring. It's a lot of money to spend on a piece of jewelry. The Cut, Clarity, Color and Carat Weight all have a significant impact on the cost of diamonds because these factors are all used to value the price and reflect the quality of diamonds. The Cut, Color, and Clarity are used to measure the quality of the diamond and the Carat is used to measure the weight of a diamond. The old saying "You get what you pay for" holds good for purchasing a good quality diamond in relation to the cut, color and clarity. Not true in respect of the carat weight.

The Carat Weight and the Quality
The Carat Weight defines the weight, not the size, of a Diamond. The price of a diamond does not increase in proportion to the weight of a diamond! The demand for a 1 carat diamond is very high and consequently, the price of a highest quality 1 carat  diamond will cost significantly more than an equivalent diamond quality weighing 0.95 carats.

Grading Reports and Certificates
Many diamond grading reports provide facts and information relating to the quality of the diamond you have purchased. A typical diamond grading report details the quality elements of Carat Weight, Size, symmetry and proportions, Clarity Grade, Color Grade and Fluorescence. If you are unsure of the quality of a diamond. your own diamond knowledge or the jeweler you are buying from then purchase a certified Diamond. The best known and reliable certification is from GIA (Gemological Institute of America) or EGL (European Gemological Laboratory). Some jewellers charge for certificates which could cost you an extra $100-$200. But having obtained a certificate would you understand the meaning of a grading report and the quality of a diamond which stated that the diamond was clarity VS2 and the color E with a faint level of fluorescence?

The Cut and the Quality
The Cut of a diamond is another important element in assessing diamond quality. The Cut refers to two separate factors. The first factor relates to the shape and style of the cut e.g. Pear, Round, Marquise, Princess, Brilliant Heart shaped etc. The second factor is the way the rough diamond is cut to produce a polished diamond which has a dramatic effect on the quality of the finished diamond. The effects of a good quality diamond cut result in the heightened levels of brilliance, fire, sparkle and luster of a diamond. The quality is also dependent upon the cut of the Diamond Facets.

The Clarity and Quality
An important quality factor is the Clarity of a diamond and relates to exactly how clear a diamond is and describes the presence, or absence, of Diamond Inclusions (flaws) within the diamond and any blemishes on its surface. The numbers, sizes, colors, locations and visibility of any inclusions or blemishes can effect the relative clarity of a diamond and its quality. The majority of diamond inclusions cannot be seen by the human eye so systems have been developed to grade diamond clarity and therefore quality as detailed in the Diamond Clarity Chart. Diamond quality on a Diamond Clarity Chart ranges from high quality, rare and expensive flawless to imperfect and cheap diamonds.

Color, Fluorescence and Quality
The Color, another important category in assessing the quality of diamonds, relates to rarity, value and quality of a diamond. The traditional color is white, or colorless, and is categorised into the following: Colorless, Nearly colorless, Faintly tinted (usually yellow), Lightly tinted (usually yellow) and Tinted (usually yellow but may progress to brownish). The color scale for colorless diamonds goes from 'D' (colorless) to 'Z' (dark yellow) check out the info contained in Diamond Color. The amount of yellowish color decreases the value of a "colorless" stone. Fluorescence can mask yellowish diamonds so that they look white or colorless in the lighting often used in jewelry shops. Extremely fluorescent diamonds are a much lower quality and can usually be purchased for 30% less than diamonds that possess no or slight fluorescence.
