A Val St Lambert emerald cut to clear trumpet vase in diagonal cut diamond shapes, model “Balzac” (1961). Signed to the base, it also has its original makers label.This vase is made of high lead crystal, meaning it is composed of more than 33% lead oxide (estimated at 40%) and not the legal minimum of 24%. This results in the highest degree of sparkling crystal with the best refraction, the sharpest cutting edges and ultimately the clearest crystal.
