For cocktail rings, sizing up a half size is often recommended because the wider base of the setting needs clearance to sit comfortably without pressing into the finger.
Origin Story
A Kashmir designation on a sapphire certificate is the trade's highest color credential: the deposit was active primarily in the 1880s through 1920s. The stones are now among the rarest in fine jewelry, and the velvety cornflower blue produced by fine silk inclusions remains the global benchmark against which all other sapphire color is assessed.
A Storied Heritage
Aquamarine's adoption as a defining Art Deco stone followed from a specific material-aesthetic alignment. The movement's characteristic palette of icy, clear colors and its emphasis on geometric structure found a natural expression in the stone whose blue was cool, transparent, and evenly distributed. These qualities perfectly aligned with the period's design values in a way that the warmer, more variable colored stones did not, resulting in its prominent use in celebrated pieces by Cartier and Van Cleef & Arpels.
