White Gold "Whiteness".
Manufacturing Jewelers and Suppliers of America (MJSA) and the World Gold Council released the White Gold Whiteness Index Monday, providing a standard of color identification for white gold.
The index was designed so that retailers, manufacturers and metals suppliers would have a common standard with which to describe white gold color. It consists of a template containing a seven-sample comparison chart that provides foil patches of controlled color, to help qualify white gold from pure white to off white.
The index, designed as a communication tool within the industry, is the fruit of 18 months of effort by the White Gold Task Force, a team of jewelers, smelters and manufacturers brought together to create a standard reference that can be applied to white gold description throughout the supply chain and around the world.
The Index allows white gold samples, either raw metal or finished jewelry, to be classified as: Grade 1, Good White, which measures less than 19 on the Yellowness Index and does not require rhodium plating; Grade 2, Reasonable White, measuring between 19 and 24.5 on the Yellowness Index, which makes rhodium plating optional; or Grade 3, Poor White, measuring from 24.5 to 32 on the Yellowness Index, and requiring rhodium plating.
While this index is interesting, the fact is that all worked Gold jewelery pieces, no matter how "white" requires some degree of rhodium-plating in the finishing process.
