How to choose a Diamond

mcc —  September 11, 2013

Jewellery Latest love diamond jewellery and it is important to know how your diamond is graded and categorised before it makes its way into your jewellery box. When buying a diamond, Jewellery Lastest wants you to be well informed to make sure you get the best product for your money. The Diamond Buying Guide provides some useful information;

Learning about diamonds means learning about the “four Cs” of diamonds which are considered the most important grades and categories:

  • Cut
  • Clarity
  • Colour
  • Carat weight

Cut is probably the most important, and most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut.

The shape of a diamond is totally different to its cut – the shape is described as round, pear etc. the cut refers to a diamonds reflective qualities – it is what makes it sparkle. When a diamond is well cut, it will be well proportioned and light will enter the diamond and reflect back off all the cut planes to make it flash and sparkle. This is called ‘ideal’. Other cuts may be too shallow or too deep. There are different grades of cut;

  • Ideal
  • Premium
  • Very Good
  • Good
  • Fair & Poor.

Ideal gives the best cut, proportions and dazzling effect while good, fair & poor have less light reflected meaning they are more inexpensive and cost saving.

Jewellers use this criteria in order to make sure you get the best diamond for your budget. Jewellery Latest recommends going to a professional jeweller who can use their expertise to grade you the perfect diamond.
