Sapphire Color Cards for better communication
Facilitating the gem trade with new tools, techniques, standards, and methodologies are one of the major goals of NGE. Communicating color information of colored gemstones has never been easier with NGE color cards.
Why it is difficult to communicate the color information accurately
NGE color cards are simply a grid of color shades you can use to compare to the color of the gemstone. The color information in photographs and videos can be misleading due to the use of various screens, surrounding lightning conditions, and brightness/contrast settings in digital devices. For example, a photograph viewed on an Apple iPhone can show a different color shade than when it id viewed on an HP laptop. Also, the color shade of a photograph taken in the board daylight can be different than a photograph of the same gemstone taken indoors.
Using NGE color cards
Consider the following example. These six gemstones were taken from the NGE inventory. They all are pink sapphires. When your seller communicates the colour they would say that the gemstone is a pink sapphire. They can be a little more specific by saying that it is a hot pink sapphire or a baby pink sapphire. Also, you can get pictures and videos as well. However, this kind of communication will not give you very accurate color information. However, if you match the color of the gemstone against an NGE color card you can assure better accuracy of color information.
The idea is that both the seller and the buyer should hold the color cards in their hand during the communication so that you can be confident that what you see it what you get.
Here are some of blue sapphires from the NGE inventory.
Not only the colors can be different from gemstone to gemstone, but a natural gemstone can also have multiple shades of colors. The following example shows some party sapphires from the NGE sapphire collection. See how each gemstone is having two distinct color shades. Color cards will come handy in describing such gemstones.
NGE training for sellers
Even the color card can give you misleading information if used in low light conditions. Low lighting causes the colors to be flattened out. This is where our seller training program is important. We have a comprehensive seller training program to teach them how to do this as accurate as possible. Completing this training is mandatory for our sellers before they begin selling in NGE platform. This gives buyers extra confidence when communicating with the NGE sellers.
How to order color cards
NGE has color cards for Blue Sapphires, Pink Sapphires and Yellow Sapphires. We are in the process of creating color cards for other gemstones such as Ruby's and Emeralds and they will be available in the future.
All the NGE registered members will get their color cards free. However, even without registering, you can order the color cards for a fee. You can order any number of color cards to be used with your own trade partners. Please visit this page to order the color cards.
