The blue pigment that makes a cobalt hue stand out refers to cobalt oxide heated and pressure treated with alumina. This sets it apart from the iron and cyanide mixture of Prussian blue or the ground lapis lazuli powder used for the creation of ultramarine deep blue. Although it was used on Chinese porcelain in the ninth century, its official European discovery took place in the early 18th century. Within the jewelry trade, cobalt blue is a distinct and highly valued hue that is a favorite with serious collectors. We have combed our inventory for our most impressive cobalt blue vintage pieces.
