GretagMacbeth Munsell Color Assurance Lab Helps Jewelry Industry Make the Grade

NEW WINDSOR, NY -- (MARKET WIRE) -- July 12, 2005 -- The GretagMacbeth Munsell Color Assurance Laboratory today announced the release of the first ever color standard for grading white gold alloys in the jewelry industry. The White Gold Whiteness Index template was developed in conjunction with Manufacturing Jewelers and Suppliers of America (MJSA) and the World Gold Council to help manufacturers, retailers and suppliers accurately grade and effectively communicate the color of white gold alloys.

"Retailers can use this template when ordering white gold product from their manufacturing suppliers, ensuring greater satisfaction for everyone," said James F. Marquart, MJSA president/CEO.

The White Gold Whiteness Index template consists of seven unique white gold color chips each corresponding to a value on the ASTM yellowness index. By visually assessing the color under GretagMacbeth standardized daylight conditions, the white gold can be categorized into three grades: Grade 1, "good white" alloys measuring less than 19 on the ASTM Yellowness Index that do not require rhodium plating; Grade 2, "reasonable white" alloys measuring between 19 and 24.5 on the ASTM Yellowness Index for which rhodium plating is optional; and Grade 3 "off-white" alloys measuring between 24.5 and 32 on the ASTM Yellowness Index and requiring rhodium plating. White gold is actually yellow gold, alloyed for color. Whiter gold is more desirable, hence a higher grade.

"The new template ends the guesswork of evaluating white gold, so you can better satisfy your customers' white gold expectations," says Daniel Ballard, national sales manager of Los Angeles based Precious Metals West and member of the World Gold Task Force.

Color is often used to determine the value of certain products. "Helping customers assess the business value of color is an important part of what we do," says Jan-Paul van Maaren, vice president and general manager, color & appearance business unit. "We're pleased to lend our color expertise to help the jewelry industry accurately assess and communicate that value." GretagMacbeth has been involved in several facets of the jewelry industry, including SpectraLight and Examolite brand daylight viewing environments for grading diamonds and precious gems. The new standard comes with an optional SpectraLight Jr. light booth or Sol-Source daylight desk lamp for accurate color viewing. It is available through the MJSA.
