MOLLY-Mae Hague's diamond engagement ring is believed to have cost a whopping £600,000.
According to ROX co-founder Kyron Keogh, the oval-cut diamond band Tommy Fury splashed out on is worth more than half a million pounds because of its "high colour and clarity".
Tommy proposed to his "soulmate" - who he met on Love Island in 2019 - on a clifftop as singer RuthAnne sang her romantic ballad The Vow.
The boxer handed their baby daughter Bambi to Molly - who was dressed in a white jumpsuit - before getting down on one knee.
Kyron told MailOnline: "Molly-Mae's engagement ring features an exquisite oval-shaped diamond that looks like 6 carats, and it if it's high colour and clarity, it could be worth an estimated £600k.
"Oval diamonds offer a fresh take on the classic diamond solitaire, making them a unique choice for those who want to break away from tradition and stand out.
"This cut has become increasingly sought after with celebrities like Kourtney Kardashian and Hailey Bieber choosing this style."
Tommy's romantic proposal had fans in tears - and said they were distracted by the size of Molly's new diamond.
The 24-year-old influencer is already making wedding plans - and has ideas for her dream venue.
She also hinted she'll be taking Tommy's surname, telling fans: "Just call me Molly Fury."
