Based on our experience of buying and selling diamonds, we have a number of suggestions, which may help in the selection process of your diamond purchase for “colour”, “clarity”, “cut” and “carat” weight. (This is commonly known as the ‘Four C’s of Diamond Buying’). Most customers appreciate some basic guidance to obtain the best value for money when choosing a suitable diamond for their particular requirements.
Deciding on the shape is the first step in the diamond selection process. Everyone has a preference for a particular shape or cut. It is extremely important to determine the diamond shape first as this can effect the final purchase price quite dramatically.
If you want to maximize the diamond purchase, while limiting the amount of money spent to a given budget then we suggest you consider a diamond with a Colour Grade of G to J. The reason for this is easy to understand. Diamonds in these colour ranges are still virtually white, or near colourless, but the prices are possibly jewelry or more below the D, E and F colour ranges. Once set in a ring or other piece of jewellery they’ll look fantastic and diamonds of this quality are used in most good quality jewellery today!
Similar savings can be applied to the diamond clarity grades. The technical Gemmological definition of an SI1 Clarity Grade, for example, states: “The Imperfection within the diamond cannot be seen with the naked eye, but can easily be seen with the aid of a 10 X power loupe”. Following this definition, if a customer purchases an SI1 Clarity Graded Diamond, they can save an additional jewelry or more over the top clarity grades assuming all other grades, Colour, Cut, and Carat weight remain the same.
Cut determines the sparkle and overall brightness of a diamond so always look out for a good cut (or a well ‘made’ stone). Learn what the specifications need to be for a great cut for your shape of diamond and then find the best value within those criteria. An Ideal cut stone is jewelry – jewelry higher in price over a well made stone. Buy a diamond with a ‘good’ cut and you will be rewarded with a stone that really sparkles!
In most cases, as the carat weight of the stone increases, so does the per-carat price of the diamond. A carat is a unit of weight which is equal to one fifth of a gram. A small diamond that weighs less than a carat is often described in points with one point being equal to 0.01ct. It is also important to be aware that a ring with a single 1.0ct diamond can be valued at more than ten times as much as a ring with a total weight of 1.00ct of diamonds made up of many smaller stones of equal quality.
Whilst this article endeavours to offer some basic guidance it should be noted that there is actually far more to buying diamonds than simply the “Four C’s to Diamond Buying”. Other things should also be considered in order to obtain a really good buy. For example the “transparency” of the stone is an important factor and any detected “treatments” will also affect quality and value. These topics will be examined in future articles.
