A 1939 Horst P. Horst photo for a jewelry feature in a magazine. Jean Harlow’s platinum blonde hair and white satin gowns set off a trend for all things white, from fashion to interior design. The white-on-white direction was also reflected in jewelry, which was remarketed as le note blanche. Gems set in platinum or white gold offered a sombre contrast to sparkling gems.
