First, try to sell the diamond yourself, to  people you know. Friends and family  members may be interested. If you don’t have  any luck with friends or family members, you  should turn to outside sources. Absolutely  avoid pawn shops! A pawn shop will only offer  you about 10% of what the diamond is worth!  Also avoid offers of selling the ring on  consignment. There are many things that  can go wrong, and there is no shortage of  diamond scams – even in well known  jewelry stores.

If the diamond is important, you should  strongly consider auctioning it off through  one of the famous auction houses, such as  Christie’s or Sotheby’s. If it isn’t what is  considered an ‘important’ diamond or a  high-end diamond, you should try to sell it  to an individual using classified ads, or even  eBay. However, selling to an individual that  you do not know could put you in danger –  especially if the diamond is worth a lot of  money.

Your final option should be a jewelry store. It  is vital that you not let your diamond out of  your sight while in the jewelry store – you  might find that the diamond you walked in  with is not the same diamond that you walk  out with! The jeweler will try to tell you that  your diamond is of poor quality or low  weight. Inevitably, there will be some  problem with the diamond. This is where  your appraisal and/or certificate will come  in handy.

If the jeweler is fair, they will offer you  between 60% and 80% of the value of the  Rapaport Value. Do not accept anything less  than this. Again, do not let the diamond out of your sight until you have been paid for it.

How Diamonds Are Mined

We seldom think about how the diamonds  we wear came to us. Natural diamonds, as  opposed to synthetic diamonds or fake  diamonds, are mined from the earth. There  are currently two methods of mining  diamonds: Pipe Mining and Alluvial Mining.

When pipe mining is used, the diamonds  are extracted from the earth through volcanic  pipes. These are not man-made pipes. These  are natural pipes in the ground. Shanks are  put into the ground next to the pipes, and  tunnels are driven into the deepest parts of the pipe.

The diamonds are not sorted out at  the mine. Instead, huge rocks that are full of  diamonds are brought out of the mine and  moved to a screening plant for separation.

The Alluvial mining method is done in  riverbeds and on beaches. Walls are built to  hold back the water and the sand on the bank  or beach is moved with a bulldozer until the  level of earth that diamonds can be found in  is reached. Again, the diamonds are not  sorted here. Instead, the sand that contains  the diamonds is bulldozed into trucks, and  taken to screening plants.
