That is quite the cushion cut diamond on Daisy’s (Carey Mulligan’s) finger. Now of course this is the ring Tom gave her, and is unrelated to Gatsby.
I read that another blogger (from NYC - FashionFoieGras) went to the main Tiffany & Co. store on Fifth Avenue to ask about the ring. Here is her report:
Before we are introduced to Carey Mulligan’s character Daisy in the film, we meet her massive engagement ring first. I made a visit to Tiffany’s. We walked in and instead of heading for the engagement ring section of the counter, I went straight for a sales assistant. “Do you have The Great Gatsby engagement ring in stock by chance?” Asking such a question I knew what the answer would be. It’s a gem, a rarity, a ring so beautiful it demands it’s own team of security guards to follow it around town. That all being said, the answer I was given from the sales assistant was stunning. She took a moment to go to the back and ask the appropriate questions and returned with an image of the ring in a look book. As she flipped to the page and pointed out the beauty I had fallen for she stated, “the ring Carey Mulligan wore in the The Great Gatsby has a value of $3.9 million. Sadly, it has already been sold so is not available for sale.”
So when I was informed that the ring was a) $3.9 million dollars and b) already sold, I used the absolute correct expression in receiving this answer. I appeared to be greatly saddened because of course who wouldn’t want to wear a $3.9 million dollar diamond ring on their finger? Apparently someone in the world right now is doing just that.
