In fact, out of all of the jeweler's in the world, only about 5% of them are bonded. Buying a bonded diamond will cost more than buying a non-bonded diamond, but when you look at what you get with the bonded option, you will see that it is well worth the extra expense.

First, bonded diamonds have a buy back policy for the life of the diamond. No matter how long you have had the diamond, you can take it back to the bonded jeweler and sell it back to him or her, for a 100% refund. If a jeweler does not offer a 100% buy back guarantee, for the life of the diamond, then you should take a closer look at the diamond to see what is wrong with it.

Bonded diamonds also have a breakage policy. If the stone breaks or chips, the bonded jeweler will replace it with a new one one time. No jeweler would ever offer such a policy on any stone that was not 100% natural, so just the offer of such a policy should give you piece of mind concerning the quality of the diamond. Bonded
diamonds are natural and untreated.

Bonded diamonds increase in value, with a fixed appreciation rate that is designed to keep up with inflation. This means that a diamond that is worth a certain amount of money today will be worth more in the future, as the price of diamonds continues to rise. This generally does not apply to buy backs, however. It typically applies to trade-ins.

Alternately, by purchasing a bonded diamond, you are protected against the possibility of a market crash. If a market crash occurs, the value of diamonds will
drop. However, the bonded jeweler guarantees to refund you the difference between what the diamond is now worth and what you paid for it before the market crash.

It may be difficult to find a bonded jeweler in your area, but if you can, this is who you want to deal with, as opposed to dealing with an un-bonded jeweler.

Specifically tell the jeweler that you are only interested in bonded diamonds. You can find a bonded jeweler in your area by using various online resources, or by calling the local jewelry stores.
