Maxwell Stone called Zara’s ring “notably understated in comparison to other royal engagement rings”.
Indeed, he valued Zara’s 1.5ct diamond ring at around £15,000, modest in comparison to the likes of Queen Elizabeth II’s, Queen Camilla’s and Meghan Markle’s.
These are estimated by Steven Stone at around £207,000, around £212,000 and around £120,000 respectively.
However, other reports have valued Zara’s ring at £140,000. The sparkler also has an element of practicality, designed so that the seasoned equestrian can wear her ring whilst horse riding.
