Bulgari's Cabochon collection gives 18-karat gold a sense of tactility to highlight the purity of the material as if it were a drop of molten metal captured in space. The design takes inspiration from the smooth cabochon cut – a signature of the brand since the 1950s – to exhibit the same sense of dynamic harmony in pieces like this ring as it does in the finest gemstones. 18kt Yellow Gold.
