WHICH DIAMOND SHOULD I BUY? Deciding which diamond to buy can be a daunting process. Generally for most people this is a significant and expensive purchase and should require some thoughtful consideration. This video from the Gemological Institute of America; GIA, is an informative tool to view about diamond grading processes. Educating yourself about diamonds is definitely the best way to make an informed choice about which diamond is the best for you. The Four C’s are the guidelines mentioned in this video. Here is a summary of what you need to consider when purchasing a diamond: Cut - Is THE most IMPORTANT factor to consider when you buy a diamond. Always look for diamonds graded very good or excellent cut. You can then be sure you are buying a diamond that is optimized for maximum sparkle. Colour - A diamond graded G and above will ensure you a buying a white, colourless diamond Clarity - Depends somewhat on where the natural flaws are located, generally though we recommend Si1 and above, with few or no flaws located on the table (top) of the diamond. Carat - Carat Weight is a personal choice that often reflects budget considerations. If for example diamond size is the most important thing to you then making sacrifices in the colour and clarity specifications is an option. However if you want a diamond that sparkles beautifully never sacrifice the cut of the diamond, choosing a very good or excellent cut is critically important unless you dont mind a dull and lifeless diamond. Certification - If there was a fifth C it would be certification. Buying a diamond graded by GIA ensures it has the specifications you are paying for.
