He catches Potter bug for her
She does not believe in wearing diamonds because of her concern about the ethics in the diamond trade.
He promised her pearls instead.
On May 10, Mr Kane Cunico, 34, a magazine managing editor, proposed to Miss Tam Su Ferne, 25, a marketing executive. They've been together for three years.
The ring he proposed with was inspired by the snitch from Harry Potter - golden wings folded around a golden South Sea pearl.
According to Mr Cunico, his fiancée is a big Harry Potter fan, who has read all the books, watched the movies and been to the Warner Bros Studio Tour London - The Making Of Harry Potter thrice.
"I was looking for some Medieval design for our ring to represent our shared love for history, but I could not find an emblem that worked as a ring," says Mr Cunico. He stumbled upon the illustration of the golden snitch on a Harry Potter DVD box set that he bought for Miss Tam.
He then went to private jeweller Juliana Foo, 35, at Ilya Diamonds, and it took around three months to make the ring.
Says Ms Foo: "We had to design the ring to follow the actual snitch closely. He wanted to do something meaningful for her and the ring symbolises how well he knows her."
Mr Cunico adds that instead of having the wings protruding from either sides of the snitch, they had the wings starting on the left of the finger and meeting again on the right.
"It is much like who we are, two different people working towards the same goal," he explains. He admits that people did not know how to react to it, since it was so different from a standard engagement ring.
But to Mr Cunico, putting more meaning into the design and story of the ring is worth more than the price of the diamond.
He says: "If the price of the ring and diamond size are the emblem for love, that's just sad."
The snitch ring is also a cheeky reference to his position as the Seeker who chases and catches the snitch (his fiancée) in the game of Quidditch.
"It has more than material value. The ring embraces the history of two people and shows that we can share what we love with each other. She made me a Harry Potter fan. It shows how I am influenced by her," he says.
