Ignore the 4Cs
Well perhaps not ignore, but do get them in perspective….
While the infamous 4Câs have known in the industry since its creation, marketing diamonds to the consumer based on these characteristics really started only in the early 1980âs. Those who still remember how diamonds were sold before 1980 will, most probably remember the advice of choosing a jeweller that you can trust and that there is no substitution to a trusted jeweller.
The 4Câs, or the physical characteristics of the diamond (Colour, Clarity, Carat weight and Cut) are appealing surety at the first glance for the concerned consumer, but these characteristics do not actually tell us much.
Ultimately you need to other expert but yourself. While the market grew before the 4Câs were introduced to the consumer, once 4Cs emerged they became the marketing pitch - instead of the character and function of the diamond itself. Many people actually lost their trust and you can argue that relatively less people buy diamonds nowadays. The market is more and more dependent upon heavy users - diamond addicts, when what we should be cultivating are connoisseurs.
I have not much experience with diamonds that are heavily flawed so my discussion will be concentrated on diamonds where inclusions are impossible to detect with a naked eye. In the language of 4Cs, these are diamonds which clarity of SI2 or better. What is possible to detect is one characteristic â the diamond size expressed in carat weight. I am aware of the anomaly of indicating the size through the weight of the diamond and will discuss it later. There is no such a thing as âbestâ size as we use diamonds according to our life style and occasion. Sometimes we will need a relatively larger diamond and sometimes, a smaller one, or a combination of several diamonds.
If you choose a diamond of which flaws cannot be detected and do not impair its performance, then I cannot advice on a âbetterâ clarity, either as all are good. Similarly, colour is a matter of personal taste. Most of the diamonds have some yellow colour in them because of the Nitrogen gas that is trapped in the crystal and the colour of them varies as it reflects the amount of gas trapped in them. In some, rarer diamonds Boron gas is trapped instead of Nitrogen and, consequently they appear blue. We have also diamonds that belong to the brown family and their colours range from brown to pink and red.
After so many years in the trade I cannot tell you what the âbestâ colour is as it is simply a matter of taste. Different skin tones and settings with other stones will also affect the way a diamond looks
.
How about cut? Originally, cut referred to the shape of the diamond: round brilliant, pear-shape, marquise, any variation of a rectangular cut and so on. The research that was done in Japan in the mid 1980âs introduced a scale based on the proportions of round-cut gems and so today we refer to the quality of the round cut when we say âcutâ instead of referring to the shape of the diamond.
Our family, S. Muller & Sons, were among the pioneers to produce what is now known as the Hearts and Arrows (H+A) cut. The story of H+A calls for a separate reflection but it is enough to know that the aim of H+A was to produce a diamond that would completely reflect the light rays directed toward it from any angle, back through the top portion of the stone creating ZERO light-loss. Based on this idea, a scale was introduced that supposed to quantify the amount and the intensity of the light reflection.
Evaluation of Cut might eventually become the most rationally evaluated quality of diamonds, beyond the broad âbest-cutâ or âexcellent-cutâ descriptions we use today. However, you should remember that diamonds have other qualities as well. One of the clear examples is those diamonds of which colours are not on the white/yellow continuum. These diamonds are polished purposely not to reflect light and, consequently, they reflect the special colour of the diamond whatever it is. There is a growing market for such diamonds, and prices can be high, although I must admit that personally I prefer the H+A diamonds that I polish but this is a personal taste coupled with some emotional attachment to a professional achievement - bringing out their reflective potential.
