Are you looking to sell loose diamonds? If so, you may think you’re sitting on a gold mine – or better, a diamond mine! However, there is a lot to know about the process of selling gemstones before actually doing it, especially if you want to be successful.

Here are a few of the factors that can impact the amount you can expect to receive in exchange for your loose diamonds – and how to choose the right diamonds if you’re looking to buy, yourself!

Carat, Color, Clarity, and Cut

Most people who are familiar with diamonds know about the “4 Cs of diamond quality”. These include the following, each of which has its own importance when it comes to the overall quality and value of the stone:

  • Carat – this is a measure of gemstone size, and the larger the stone, the more valuable it typically is.
  • Color – The closer to perfectly colorless a diamond is, the more valuable it will be.
  • Clarity – In general, the fewer flaws a diamond has and the clearer the stone is, the more valuable it will be.
  • Cut – Some shapes of diamonds are more valuable, and the quality of the cut can also increase the value.

Inclusions or Unique Qualities

An inclusion in a gemstone is technically a flaw or imperfection, but just as human imperfections make each unique and beautiful, so too can inclusions in diamonds. Look for unique qualities that don’t detract from the overall quality of the stone.


When selling diamonds, it can help to get your stone graded or appraised professionally. This will build buyer trust and guarantee the quality of the stones you are selling.

The best advice any industry insider can offer is to always work with a reputable retailer. When looking to buy or sell loose diamonds in NYC , always work with a retailer that partners directly with the Gemological Institute of America – or GIA – to ensure the quality of the appraisals and stones they are selling or auctioning. This way, both buyers and sellers will be protected during the transaction – and you can expect the very best from your exchange!
