Ramat Gan, Israel--Briza Color Diamonds is now offering a service that can turn polished white diamonds into color-enhanced diamonds, thereby upgrading the value and improving the price of the stones.

According to a release from the Ramat Gan, Israel-based company, Briza's proprietary technology uses an electronic accelerator to simulate the conditions that exist in nature to produce natural-color diamonds.

"Up until now, we have mostly concentrated on supplying colored diamonds," Briza owner Amnon Barak said in a media release. "We have established a reputation for providing excellent product and consistent quality. Now we are offering this color-enhancing service to other diamond companies."

The process, which utilizes the color that already exists in a diamond, has been developed to a point that enables Briza to offer consistent results in 14 colors, according to the release.

"The diamond is not only carbon but has other elements inside," Barak said. "The foreign elements mixed in with the carbon create color centers in the diamond. Under proper conditions, these are enough to create the desired color."

The company's color catalog includes varying shades of black, blue, cognac, gold, green, orange, red cherry and yellow; Briza also can produce pinks.

The service also includes expert advice as to what color each diamond can produce and which stones are economically worthwhile to color.

The technology enables diamantaires to offer colored diamonds at an attractive price and also gives designers the freedom to work with a wide array of hues, according to Briza.

Major gemological laboratories recognize Briza's process and they can provide their own certificates or those of the European Gemological Laboratory or the Gemological Institute of America.

In addition, Briza provides a price list to serve as a guideline for the service.
