The most important step in determining the value of your diamond is to know its characteristics. This includes carat weight, shape, clarity, color, cut and some secondary factors such as fluorescence. If your diamond is certified or came with a detailed appraisal, this should be a simple process. If not, you can use our Diamond Information Center to ascertain some of these characteristics yourself. The more information you have, the more accurate your value estimation will be.
Another way to accomplish this would be to take it to a certified gemologist. Most stores will charge for this appraisal service. Be sure to inform the appraiser that you want an honest interpretation of your diamond’s quality, (they often inflate values and quality in order to indulge their customers).
You could also take it to a qualified buyer. Even if you don’t intend to sell it they should be able to provide an accurate breakdown of your diamond’s characteristics.
The next step is to search for similar diamonds being sold online. There are numerous online retailers whose websites include a searchable diamond database. The most extensive Is Blue Nile. You can use their diamond search to locate a diamond with similar characteristics to your own. Here is a link to their search: www.bluenile.com.
Once you have found a close match, take note of its price. This price should reflect the retail value of your diamond. By deducting 25-35% from this figure, you should get a reasonable resale target. This will give you a starting point when meeting with potential buyers and will help you to make an informed sale decision.
