Colored Diamonds

Fancy colored diamonds are all the rage these days. Gemologists have developed new ways to create versions that are affordable for the average person - by treating less desirable diamonds. These less desirable diamonds are treated with irradiation followed by intense heat. This turns brown and yellowish diamonds into beautifully colored diamonds that you can afford. This produces stunning greens, blues, yellows, reds, purples and other colors. These colors are considered permanent, but there is a possibility they could change during repairs if a high heat is used.

Treatments like irradiation make it possible for more people to own these vividly colored diamonds. Most natural colored diamonds are rare and also extremely expensive. When shopping for colored diamonds you need to assume that any affordable fancy color diamond has been treated. Ask about the stones origin and request to view a lab certificate to verify authenticity.

Synthetic colored diamonds are another option if owning a colored diamond is something you desire but cannot quite afford. They are real diamonds, but they are created in a lab.

Natural fancy color diamonds get their coloring from different trace elements present in the stones, such as nitrogen, which produces a yellow diamond. Diamonds can be colored by exposure to radiation during its creation. An example of a diamond affected by radiation is a Green diamond. 


Another way that a natural colored diamond gets color is by its inclusions. Regarded as flaws and undesirable in a colorless diamond, inclusions give unique tones and brilliant flashes of color in a fancy color diamond. Remember that Natural fancy colored diamonds are very expensive, any colored diamond labeled to be sold as natural should be accompanied by a certificate from a respected grading lab. 


A "fancy" diamond is a natural diamond that has color. These colors vary from red, green, purple, violet, orange, blue and pink – and most shades between. Fancy color shades vary from faint to intense.

The most famous diamonds in the world are Color diamonds. The Tiffany Diamond, which is yellow and the Hope Diamond which is blue are colored diamonds. Color diamonds have an amazing financial track record. The value has never decreased on wholesale level in more than 30 years. Blue and pink diamonds have doubled every 5 years of a strong economy. In the 1970’s  you could have bought a very high quality blue diamond for about 50K and today the very same stone would be worth between 2 and 3 million.

Diamond Certificates

Diamond certificates from independent organizations such as the Gemological Institute of America (GIA) provide a diamond grading report, that gives you valuable information about the 4 C's that were taken into consideration when the diamond was priced. It's important that you use an outside source for diamond certificates, instead of the jeweler who is selling the diamond you are interested in, because the jeweler wants to make money on the sale of the diamonds, the certificates may be slightly biased and you could be paying more than the market value of the diamond.

Reasons to have Diamond Certificates

When you go to a jewelry store, or consider making a purchase from an online retailer, the jewelry that has diamond certificates tends to sell for several hundred dollars more than diamonds that are graded the same that are without certificates. This is because the jeweler recognizes that they typically grade their diamonds one level better than an independent grading organization, like the Gemological Institute of America. The GIA is more conservative when grading diamonds because they do not gain anything from diamond sales.

Pay the Right Price for your Diamond

Diamonds are valued according to their quality based on a grading system that makes use of the 4 C's. You should receive diamond certificates (also called grading reports) from independent companies rather than a jeweler, to insure that your getting an unbiased reporting of the value of the diamond. Otherwise, you could be paying much more for your diamond than what the diamond is actually worth.

Protecting Your Investment

Diamonds are not the same kind of investment as buying stocks and bonds, but having diamond certificates gives you a better investment than just having the diamond. Diamond certificates make it easier to sell a diamond in the future, because you have documentation of how much the diamond is worth and why it was valued that amount. In fact, if you attempt to sell diamonds without having diamond certificates, most dealers will not buy from you and you would end up having a certificate drawn up anyway, so you may as well have a certificate grading report created at the time of purchase, for your current protection as well as future possibilities for selling.

Increased Security during Cleanings and Repairs

Many people hesitate to bring their jewelry into the jeweler's when they're in need of repair services or cleaning. It makes people wonder how they'll know for sure that they've received the same diamond back that they brought in. It is an extremely rare occurrence for a jeweler to purposely switch diamonds, however it could happen unintentionally. Diamond certificates act as an additional security measure in this case. They are like fingerprints stored in police databases, they contain all the data needed to match the person to the fingerprints, and diamond certificates have enough information on the diamond to match the diamond with the certificate and the owner.
