It was later looted by Sweden throughout the Thirty Years’ Struggle and ultimately given as a present to Catherine the Nice. However throughout a listing of the Russian assortment in 1922, the mineralogist Aleksandr Fersman made a stunning discovery: Caesar’s Ruby was, in truth, a rubellite tourmaline. Whereas labeled as semiprecious, such tourmalines, which derive their coloration from manganese, are literally rarer than rubies. By mixing deep scarlet rubies with tourmalines, which have a tendency to return in shades of tender rose, in a pair of pink gold chandelier earrings, Bulgari, the 138-year-old Rome-based luxurious model, has created an explosion of shimmering coral reds that hint the curve of the neck. Caesar’s Ruby captured the world’s consideration with its depth of hue; these earrings refract that legacy in a chic cascade. Bulgari Tourmaline Blossom earrings, value on request, bulgari.com.
