Using The Coating Method to Enhance The Color of a Diamond
Thursday, December 30, 2010 by admin
What you see may not be what you get, is the motto used with any color enhanced diamond that has undertaken the coating method. It is just another way to produce color enhanced diamonds without having to pay outrageous prices for an authentic fancy colored diamond, or rare natural colorless stones.
Coating a diamond is done nearly always to actually deceive the buyer into buying something they think is natural, when in fact it is a bad imitation at best. It is done to mask the yellowish tints in a natural diamond, and of course to raise the value.
In past years every attempt was made to find a way to coat a diamond without being detectable such as adding colored metal foils to the diamonds before they were set, or coating the diamond with nail polish. Today, modern technology has made it more possible to coat a diamond by applying super thin layers of a more durable coating solution. Although no one can say what material is being used, it is something that lasts longer than previous solutions. In fact, a coated diamond can go undetected for many years if it is not graded by a reputable lab, or professionally cleaned on a regular basis.
A lay person will probably not notice if their diamond has been coated, so it is important to look for the signs. If you don’t receive a certificate of authenticity, or if you see spots of color on the girdle or facets that don’t look the same as the top of the diamond you may have reason to be concerned.
