2) Different types of diamonds

Diamond is the most precious stone in the world. Indeed, many have been fascinated with the beauty and uniqueness of diamonds. They are often expensive depending on the colour, clarity, size and shape. Diamonds are mined from different part of the world, including Russia, Australia, Africa and a few more.

There are different categories of diamonds. Just a reminder that not every diamond is natural. Indeed, natural diamonds have a higher value than human-made diamonds. The white, transparent and inclusion-free diamonds are the most valuable. Treated diamonds to enhance colour and clarity have a lower value. Human-made diamonds called Masonite are used to keep the cost of manufacturing individual jewellery low; however, does not have much resale value.

Fancy-coloured diamond vary in colour, and their colour determines the price of these diamond, not all colour has a high value.


3) What are carat, colour and clarity?

When you think of diamonds, you often think of carats. They represent the weight of the diamond. The carat of a diamond determines the price of any given diamond. To keep it simple 1g is equal to 5 carats in diamond weight

When it comes to identifying the clarity, a professional would have to use Technics and specific tools to identify the colour. The colour range from D to N, where D is the topmost white colour and N has a very yellow tint to it. Depending on the shade of yellow, a diamond is classified as Fancy Yellow or just a low-colour diamond. An untrained eye can not identify the colour of a diamond. 

Often you use a microscope or a loupe to check the evidence of flaws and imperfections in the diamond. These imperfections are called inclusions.

The specific scale associated with the ranking system, which is provided by the GIA is as follows:

  1.  IF: Internally Flawless
  2. VVS: Very Very Slightly Inclusion
  3. VS: Very Slight Inclusion
  4. SI: Slightly Included
  5. I: Included
    Identifying most inclusions through a loop is difficult. In these cases, diamonds are more likely to be of higher clarity and hence, a higher value.

If you are hoping to sell a diamond or some diamond jewellery, there are some things you should be aware of which we will now mention.

Tips for Selling Diamonds

Here are some tips you should follow before selling diamonds:

  1. Provide A Certificate Of Authenticity
    Whenever you sell your diamonds, the interested party will ask for a certificate of authentication to verify that your diamond is original. Therefore it is important to have a certificate from a gemological laboratory.
  2. Be Aware Of The Value Of Your Diamond
    In other words, know what you have got. Every diamond has a unique characteristic which you should be aware of. You should also know about the weight and carats of your diamonds, so you know their exact value. That would make the decision of selling easier for you as it will help you recognise a good deal.
  3. Do Not Have Unrealistic Expectations
    Know that the buying parties will most likely pay you less than the market value of your gem. The fact that they are re-sellers who want to make a profit by selling off your diamond again. It would help if you had realistic offers in mind, so you are not disappointed when you enter the market.
  4. Research The Available Options And Choose A Trustworthy Buyer
    There will be plenty of options when it comes to finding buyers for your diamonds. The quickest and easiest buyers would be jewellery shops, pawnshops or companies who specialise in stones and precious metals. There are many of those so you should be aware of their reputation and make sure they are trustworthy. Another aspect can be the amount they pay and the ease of selling through them.
