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 Ā£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 Ā£207,000, around Ā£212,000 and around Ā£120,000 respectively.
However, other reports have valued Zara’s ring at Ā£140,000. The sparkler also has an element of practicality, designed so that the seasoned equestrian can wear her ring whilst horse riding.
