Have you heard about it? My jewelry designer told me that it''s a patented metal used to mix with pure gold to arrive at 18K white gold that actually helps the gold to stay silver white and no plating required. He said it''s not palladium, and he doesn''t recommend it either because it''s soft than 18K gold. Platinum has the silver look but not shiny once you wear it for a while, this Ultra White Gold can be shiny and white. I searched the internet but didn''t find any info on it. Any thought?
