According to Leane, Edoardo was heavily involved in crafting the unique ring.
“Edo was very prepared and he had done his research. He had a very strong feeling about what he wanted,” said Leane, adding that his love of Art deco designs influenced the design.
“He knew that he wanted a round stone, and he knew he wanted platinum. We talked about aesthetic and he said, ‘I really love Art Deco, and Beatrice really likes a Victorian aesthetic in jewellery.’ We talked about fusing the two together and he thought it would be lovely to do that, to fuse their two personalities together within the ring. There was a real unity.”
Leane said the diamond engagement ring was crafted over five to six meetings adding that the property tycoon "came with thoughts and then I would relay those thoughts into sketches."
"He personally chose the stones. The ring was crafted upstairs with my goldsmiths. With our bespoke service, we document every single stage of the ring so throughout the whole process I would mail Edo the pictures of the ring — there was a constant communication."
The 31-year-old daughter of Prince Andrew got engaged to the 34-year-old in Italy earlier this month.
The couple released a series of pictures (taken by Beatrice's sister Princess Eugenie) with their arms wrapped around each other, looking more in love than ever, to announce to the world that the royal wedding will be held in 2020.
"The Duke and Duchess of York are delighted to announce the engagement of Princess Beatrice to Mr Edoardo Mapelli Mozzi," the royal family Instagram account read.
Princess Beatrice and Mr Edoardo Mapelli Mozzi said: “We are extremely happy to be able to share the news of our recent engagement. We are both so excited to be embarking on this life adventure together and can’t wait to be married."
Princess Eugenie and Beatrice's mother Sarah Ferguson also congratulated her the bride-to-be in an Instagram post.
