Diamond With a High Resale Value

Buy Certified, Sell Certified

When you buy a diamond, it’s important to make sure that it comes with a Diamond Grading Report from a reputable diamond grading laboratory. The most commonly used and well-recognized laboratory in the USA is the Gemological Institute of America, or G.I.A. Well-respected laboratories like the G.I.A. perform independent inspection and testing on each diamond they receive and certify that the stone is a certain Color, Clarity, Carat Weight, Cut, and much more. This certificate is an essential tool for the customer when buying a diamond; otherwise they have no way of determining the true characteristics, and therefore value, of a diamond.

Similarly, it’s important to keep the diamond certificate with you to show the store or diamond supplier you are selling to. Without a certificate, you have to rely on the sales associate’s word on the color, clarity, etc. of the stone, and you could be offered a lower price than you wanted to sell for. A diamond grading report is an essential tool in determining the true value of your diamond, and is your best bet at getting a proper resale value for your diamond.

Check the Inscriptions

Many laboratories, including the G.I.A., have options to laser inscribe the diamond certificate number onto the girdle of a diamond. Under a microscope, you can then see this certificate number and easily tell that the diamond matches the diamond grading report. Without a laser inscription, it can be difficult for both the customer and the retailer to determine if the diamond matches the grading report exactly. A laser inscription is a quick and accurate way to match a diamond and its corresponding grading report.This will remove any doubt that the diamond does not match the certificate and will increase resale value.

It’s also important to keep in mind that some companies laser inscribe their own logos or trademarks onto the girdle of the diamond, next to the certificate number. This tends to reduce resale value, since a company is going to be unwilling to sell a diamond with another company’s logo on it. Your best bet is to only purchase a diamond with a diamond certificate number laser inscribed onto the girdle, and no other inscriptions. Most diamond grading reports (including the G.I.A.) will list all inscriptions present on the stone at the bottom of the certificate.

Choose Your Diamond Shape Wisely

When buying a diamond, it’s important to remember that certain diamond shapes are more costly when in high demand, and that they will lose value if demand for that shape falls. A good example is the marquise diamond shape. During the early and mid 90’s, marquise diamonds were very popular and were therefore more expensive. During the early 2000’s however, public demand for marquise diamonds fell drastically, and so did their resale value. Consumers who purchased a marquise diamond in the early 90’s and sold it in the early 2000’s saw a massive drop in the resale value of their stone.

It’s always important to buy the diamond shape that’s most appealing to you and your loved one, but if you are open to many options I would always recommend buying a round diamond. Round diamonds (also known as Round Brilliant Cut) have been the most popular and widely purchased shape for decades, and they have relatively stable price values when compared to other shapes.
