Bakker Diamonds - Custom Made Jewellery

Diamonds may, as they are forming deep within the Earth, include other foreign materials which become trapped within the pure crystallised carbon. Also, some carbon atoms may not be converted into diamond crystal, unlike their surrounds. These may appear as tiny almost invisible flecks, feathers or marks or in the case of heavily ‘included’ stone may be obvious to the naked eye. These marks, large or small, can be described as ‘birth marks’ or fingerprints and make a diamond wonderfully unique. Unless specifically requested by a client, Bakker Diamonds will not sell a stone that has visible inclusions…….our preferred clarity grades are from VVS through to SI.
At the top of the clarity scale is ‘F’ or flawless, and this simply put, means no internal inclusions or external blemishes are visible under a jeweller’s hand-lens magnification. The fewer the inclusions, the clearer and more brilliant the diamond. At the bottom end of the scale is Pique grade 3, Pique a French word meaning ‘marked’ or in this case “included” (I3).
Slight inclusions within a diamond do not reduce its durability or affect its beauty.
This internationally recognised scale states the rarest and most valuable colour of a diamond is ‘D’ or colourless. Most diamonds we sell fall between D and H colour range while most rough diamond material mined has a very slight yellow, brown or grey colour. Apart from fancy coloured diamonds (pink etc), absolute white (D colourless) is the best and rarest colour nature offers. As we look down the scale, the colour drops to a slight straw colour of yellow and onto an obvious yellow. Most customers are seeking to achieve the best value for money and this is why the most popular colours chosen are from E through to H ( the straw colour begins at colour I ). The range EFG tends to offer very nice white material and suits most people. Those prepared to spend more may venture into the top D colour. Once again, this quality plays an important part in the valuing of a diamond. The more yellow the stone the more available and less valuable. Most diamonds viewed in jewellery windows today would fall somewhere between ‘F’ to ‘I’ colour.
Carat is simply the international weight measurement used when weighing gemstones. This is not to be confused with ‘gold karatage’ describing gold purity eg 9 carat, 14 carat, 18 carat etc.
A one carat gemstone is equivalent to 200 milligrams. One carat is divided into 100 points therefore a 1/2 carat diamond is described as .5 of a carat, or 50 points, or a ½ carater.
The heavier the diamond, the rarer it will be within the marketplace, however the other qualities must also be considered for it to be compared and than valued. For example a 2 carat diamond with very, very slight inclusions (VVS) is rarer and more expensive than a 2 carat slightly included (SI ) stone.
Fluorescence is a characteristic that makes some diamonds appear to change colour when they are exposed to ultraviolet light.
