(NewsNation) — Taylor Swift and Travis Kelce announced their engagement Tuesday, with the music superstar showing off her massive engagement ring. 

In a joint Instagram post, the pair wrote, “Your English teacher and your gym teacher are getting married.”  

“The Miss Americana” star’s ring, an old mine brilliant cut with a gold band, was designed by Artifex Fine Jewelry’s Kindred Lubeck, according to E! News. 

“The style of the ring is definitely a throwback to the Victorian Era, with the beautiful, delicate and decorative gold work,” Benjamin Khordipour at Estate Diamond Jewelry told Brides.com.  

“Taylor Swift was proposed to with a stunning elongated antique cushion-cut diamond that is approximately eight carats, F color, and VS1 clarity,” Khordipour said. “The ring was handcrafted in 18k yellow gold and the center diamond is set with needle point prongs that perfectly match the antique style. Smaller diamonds and hand-engravings adorn the shoulders of her setting.” 

Taylor Swift engagement ring’s likely cost 

While the actual cost of the ring hasn’t been revealed, jewelry experts have given estimates between $500,000 to nearly $1.3 million.  

“We estimate the price of her ring to be $550,000,” Khordipour told Brides.  

Nilesh Rakholia, founder of diamond jewelry manufacturer Abelini, estimates the higher end. Rakholia told Us Weekly he estimated the ring to be worth $950,000 to $1,270,000.  

“The stone itself looks to be easily in the 7–10 carat range, which immediately places it among the most iconic celebrity engagement rings,” Rakholia said.
