From that moment on, the world couldn’t take their eyes offCatherine’s unique engagement ring.

However, it dates back much further than their ill-fated 1981 nuptials.

Made from 100% pure Welsh gold, this piece ofjewelry was also a royal family heirloom.

Additionally, the fashion-forward Catherine also modified the sapphire studs by having them redesigned into a high-hanging drop style.

With the help of Prince William and his refined taste in jewelry, it seems the young wife succeeded.

Catherine’s watch is so special that it even has its own name the Ballon Bleu de Cartier.

To make this gift even sweeter, seems like William owns a matching masculine version the Omega Seamaster 300M.

However, another theory could be that the royal family simply has a penchant for pink diamonds.

However, the earrings retain a classic feel by being circled in a series of diamonds.

To top it all off, the entire set is placed in 18-carat yellow gold.

In New Delhi, India, for example, Catherine debuted the pieces alongside a beautiful turquoise gown.

These lovely pieces are easily identifiable by their unique bell cap design, from which two chunky pearls hang.
