If you try to sell engagement rings or other types of diamonds, it is also important for you to consider the value of all jewelry. Going to a jewelry store is a way for you to set that price, but you also have to consider the value of the rest of the jewelry and not just the gemstone. You can search for the best place to trade jewelry on the web to get the best jewelry.
It is also important for you to avoid the temptation to go to the nearest pawn shop and try to get a good price on diamonds. Most likely, you will get the lowest price available and even though they may need to save it for a certain period of time, it will quickly disappear once the time is over. You will get a very low percentage of the true value of diamonds when sold through such resources.

If it's gold, you might be able to get a decent price if there is a lot of gold in jewelry. Make sure you check the possibility and then sell the stones separately to make as much money as possible.
Finally, you have the option to use an online broker who will buy diamonds from you. Just make sure they are willing to give you an estimate of how much you will receive from the purchase. It is a better idea for you to have someone who buys a diamond directly then tries to sell it with shipping.
There are many problems that can arise when you put a diamond on a shipment including the possibility of not getting money and getting a different diamond when returned.
