The four ‘C’s, carat, clarity, colour and cut are all you need to know when it comes to buying loose diamonds. All you may ask but if you about to spend a serious amount of money (and with a diamond that is likely) then you need to know what you are looking for. You can obviously go to an expert but you need to be certain that the advice you get is impartial and not based upon that person’s wish to sell you something. There are many reasons for buying a loose diamond. It is most likely you have something in mind, perhaps creating a piece of jewellery rather than buying a setting you have seen in a shop? There are plenty of online diamond sales outlets concentrating on loose diamonds. Here are a few things you should consider, divided into the four ‘C’S.
The carat, otherwise known as the weight, is the most important factor when it comes to value. The bigger the carat the more valuable is the stone; it goes without saying. The value cannot be calculated per carat. Large stones are rare and with all other things equal the value will rise exponentially. Just recently a man found a diamond of more than 6 carats in Arkansas, a rarity indeed and certain to be bigger than something you are looking for.
There is an argument that clarity is the least important of the ‘C’s. After all as long as the diamond looks good to the naked eye that is surely sufficient? If you are buying at the right price you won’t lose anything if there is a lack of clarity. If the diamond sparkles when you wear it then you should want no more.
Pure diamond has no colour at all; the colour comes from the impurities within the stone. Sometimes the colour can actually detract from the value of a stone. A white diamond with too much yellow hue will drop in value while the rare pink or blue stones will be more valuable than the standard ones. Colour is still interlinked with the other important elements. Some colours reflect light better dependent upon the cut you select. It is a balancing act.
The cut you might want is purely subjective. Certainly an expert cutter is likely to know how best to present a specific stone, how best to use the light to bring out its brilliance. The most common cut is round. In any event the less waste there is from cutting the more value you will still have in your stone.
You should at least know what general questions to ask from learning more about these general issues relating to diamonds. In the end you will want value for money but a decision about a diamond is very subjective. Are you looking for an investment or is your priority simply to have a lovely piece of jewellery?
