A diamond's refractive index is among the highest of any colorless natural gemstone: light bends more dramatically inside it than most competing materials, which is why the brilliance is in a category of its own.
A Storied Heritage
Design movements rarely set out to change how pendants attach to chains. But when fine jewelry's broader aesthetic shifted toward cleaner, less ornamented surfaces in the latter half of the twentieth century, the bail loop became conspicuous in a way it hadn't been before. The concealed bail was, in part, the industry's answer to its own evolving standards.
A Notable Quality
10kt yellow gold's slightly warmer, more muted tone compared to higher-karat gold is worth considering if the piece will be worn alongside 14kt or 18kt karat jewelry. The difference is most visible in direct comparison, and whether it matters depends on how closely the pieces will be worn together and how much metal color matters to the wearer.
