Although caveat emptor is stressed upon all over the world for the buyers to be aware and informed about the dealings and transactions that they are going to be making; it is good to make some exceptions now and then as per case.

It is not very unusual for people to be taking advantage of the unused gemstones kept in their vault or the old diamond jewellery lying in their trinket box that they do not find of any use anymore.

Buying and selling of diamonds and jewellery is a very common practice, but one that needs to be done very carefully and with caution. You do not always partake in selling your diamonds, and it is mostly a once in a blue moon thing for many. For this reason, we are making an exception of caveat emptor so that you as a seller in this case, are informed about the decision that you are going to make.

There are chances, though very low, that someone will underhand you and pay you less for your precious gemstones; that would actually value a lot more. Or there may be cases where you do not know the worth of your gems, and would sell them at an undervalued price.

This is why we have for you a checklist of 5 things— that you need to consider before you sell your diamonds or any other precious gemstones in the market. Everyone wants to get the most out of the deal!

  • Know the 4 C’s:

Diamond or any other gemstones are identified and assessed by the 4 C’s – 

  • Cut – A diamond cut means how well the diamond is cut for its facets to interact with light to create visual effects like brightness, scintillation, and the scattering of light. Some of the popular diamond cuts include the round brilliant, pear, oval, emerald.
  • Clarity – Another way that your diamond gets assessed is by its clarity. The clarity refers to the absence of inclusions and blemishes. This clarity scale is divided into 6 categories for a total of 11 grades.
  • Flawless (FL) No inclusions and no blemishes visible under 10x magnification
  • Internally Flawless (IF) No inclusions visible under 10x magnification
  • Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
  • Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under magnification, but can be characterized as minor
  • Slightly Included (SI1 and SI2) Inclusions are noticeable under magnification
  • Included (I1, I2, and I3) Inclusions are obvious under magnification which may affect transparency and brilliance
  • Colour – The colour of your diamond is evaluated based on the absence of colour. A good quality diamond is pure and clear like water – colourless with no hue. The colour is graded in range from D to Z, with most diamonds falling in the between D to M ranging from colourless to faint yellow.


  • Carat – The carat is the standard unit of measurement used to indicate the weight of diamond and precious gemstones.


  • Self-Appraisal:

After you have understood the 4 C’s of assessing diamond, you yourself can first try to identify what quality of gemstones you possess. Go to your local jewellery stores and pawn shops to do some comparisons. This will give you an idea about the price. You can even look up online on various financial sites to get an idea about the worth of your stones.


  • Professional Appraisal:

Now that you have done some research from your side, it is good to get it checked from a professional too. They know how to assess diamonds and other gemstones properly to point out any information that you may not know. At Diamond Brothers, we provide a free valuation service and also provide you with the best offers for your goods. Accepting or declining our offer is at your liberty and you will have no obligation to sell it to us.


  • Research your buyer:

After getting your diamonds assessed properly, you may have come across a few prospective buyers with some even offering you the best deals for your diamonds. Do not get tempted and swayed by these offers. Research your buyers properly first. Go to their website to check how reputed and genuine they are. Read reviews and check their ratings to see if they are really trustworthy.


  • Legal Protection:

Lastly, another important thing is to make sure you are legally protected. Have all your certificates ready with you, if you have any. Find out the various modes of payment being offered to you and the time taken for the whole transaction to take place before you get the payment. Get any doubts clarified before getting into any agreement or signing any contracts.

If you or anyone that you know are planning to sell their diamonds and/or other gemstones that have been lying unused or that they do not find use for anymore, make sure that you go over these 5 points discussed above to make a perfect deal.
