The diamond on Taylor Swift’s wedding ring finger has people wanting to know more.

A close-up of the sparkler Tuesday was among five photos that accompanied Swift’s engagement announcement with Travis Kelce on Instagram.

Mordechai Yerushalmi, owner or The Jewelers of Las Vegas, says it looks like an "older cut".

“Most people are attracted now to the older stuff and you see, I can see that a lot of jewelry that I was making in the 70s and 80s, a lot people right now are asking for it.”

And Yerushalmi would know, his Las Vegas store is covered in photos of celebrities who have come in for pieces since the 1970s, including the late Elvis Presley.

Yerushalmi says he now expects an increase in demand for this cut of diamonds, a trend he's seen "many times" following previous celebrity rings.
