The central part of Brilliant's mother-of-pearl dial is a medallion set with diamonds. The entire bezel is set with more diamonds. Its indices are yet more gems, but of a special cut. The kite-cut is extremely rare, exclusive and a Jacob & Co. signature. From that canvas, Jacob & Co. has designed dozens of uniquely colored variations of Brilliant, creating its largest, most diverse collection. Brilliant is Jacob & Co.'s ultimate expression of femininity.
