  • 8 Ways To Identify A Fake Diamond [Infographic]

    A diamond can be a girl’s best friend but can also be her worst enemy...that is, if the stone turns out to be fake. Whilst the only way to guarantee the authenticity of a stone is to have it appraised by an independent gemologist, knowing the warning signs of a fake is often a great indication as to whether it needs a visit to a professional.

    Here are 8 ways to identify a fake diamond, providing a simple and straightforward process to help spot the warning signs:

    How To Identify A Fake Diamond

    1. Check The Certification
      Any genuine diamond should come complete with a certificate from a grading authority to verify its authenticity. Such a certificate should include everything which needs to be to known about the stone, including the cut, carat, clarity, colour and more.
    2. Check The Reflection
      The reflection of a genuine diamond will have different shades of grey and white on the inside and light rainbow colours on the outside. A fake diamond will have rainbow reflections on the inside.
    3. Do The Fog Test
      Breathe on the diamond and watch how quickly the fog clears. A genuine diamond can disperse heat rapidly and, as such, the fog should clear almost instantly. Fakes will usually take at least 2 seconds to clear.
    4. Check The Refractivity
      The refractivity is a diamond’s ability to bend light which passes through, contributing to its brilliance, something which cannot be replicated. Place on a newspaper. With a fake, it will be possible to read the print through the diamond but not with a genuine one.
    5. Do The UV Test
      The majority of diamonds have a light blue hue when under UV light. Test a diamond by using a UV lamp to look for this blue hue, taking note that not all diamonds will have this. As such, not all stones without this characteristic will be fake.

    6. Check For Imperfections
      Using a loupe, check for imperfections. A fake stone will be perfect, whilst a genuine diamond will display a number of imperfections due to the fact that it came from nature. These imperfections are known as inclusions.

    7. Do The Sandpaper Test
      Rub the diamond with sandpaper and look to identify whether it has scratched the surface. A real stone will remain perfect after being scratched given that it’s one of the world’s hardest materials yet a fake will scratch up.
    8. Check The Setting & Mount
      A real diamond is unlikely to be set in a cheap metal and this can be one of the easiest ways to identify a fake. You would generally expect to see a diamond set in either real gold or platinum yet a fake in a cheaper, inferior metal.

  • Understanding The 4 C's Of Diamonds

    Almost everybody is familiar with the term ‘the four Cs’, but how many of those familiar with the term actually know what the four C’s refer to or how they are used to assess the value of a diamond?

    Cut

    The term ‘cut’ when used to describe an attribute or quality of a diamond refers to the specific and unique shape of a stone.

    The way by which  diamond is cut affects and to an extent determines how light that enters it will to exit and so showcase the stone. For example, a cut which makes the best of a diamond and its proportions (hence, an ‘ideal cut’) will bear a complex arrangement of facets which combine to reflect as much light entering a diamond back into the eyes of those who perceive or see it. The less light which is reflected back into a person’s eyes when gazing at a diamond the less ‘brilliance’ the diamond will have.

    Carat

    Carat is a measure of a stone’s weight. Then, just as with any valuable substance the earth yields, the thinking is: ‘the more the better’. Further, because larger single diamonds are far rarer than smaller examples, the monetary value of a diamond increases exponentially according to its size.

    So, and in summary, when somebody shows you their new diamond ring and speaks about its carat, they are speaking about the weight and size of the stone and not commenting on the quality of its cut, clarity or colour which too will be relevant in assessing its value.

    Clarity

    When assessing the clarity of a diamond one is concerned with the ‘flaws’ the stone contains. To the naked eye often these flaws themselves often seem invisible, but diamonds which bare fewer flaws as such bare more ‘brilliance’. Hence, the clarity of a diamond will affect the way it looks to the naked eye.

    Almost no stone is ‘flawless’; this is true even of diamonds. Hence, a diamond’s clarity is assessed to determine how ‘imperfect’ a diamond is in order to assess its value.

    Colour

    ‘Colourless’ diamonds are by far the most highly valued diamonds in existence. Why? The answer lies, as any gemologist or jeweller knows, in the fact that colourless diamonds permit the highest refraction of light. This refraction of light is, by non-experts, most commonly referred to as a diamond’s ‘sparkle’.

    Hence, coloured or ‘off-white’ diamonds, whilst they do exist and are valuable, are less so because they absorb a portion of the light that reaches them. Consequently, this ‘dampens’ or ‘dulls’ their sparkle.

    To learn more about ‘the four Cs’, refer to the Diamond Buying Guide website, which features both information and diagrams to introduce buyers to the art of diamond cutting or take a look at this great infographic which does a great job of outlining in simplistic terms just what each 'C' means.
