Travis Kelce knelt to the ground and pulled out a (massive) ring for Taylor Swift - and Us Weekly has all the details. The couple took to Instagram on Tuesday, August 26, to share photos of their engagement. In one pic, Kelce, 35, held hands with Swift, also 35, while showing off her new rock. The ring featured an old mine brilliant cut diamond set on a gold band with more small stones. Designed by Kindred Lubeck at Artifex Fine Jewelry, the design was complete with a thin bezel. (An old mine brilliant cut dimaond is a pre-modern stone that is characterized by its imperfect symmetry, cushion shape and chunky facets.) As for the cost, jewelry expert Nilesh Rakholia estimated the ring to be worth $950,000 to $1,270,000. The Abelini founder told Us, "The stone itself looks to be easily in the 7-10 carat range, which immediately places it among the most iconic celebrity engagement rings." Another jeweler Laura Taylor, who specializes in engagement and wedding rings, told Us that the ring could be up to 12 carats. Taylor agreed that it was "easily worth" $1 million.
