Taylor Swift was photographed on her birthday wearing what appears to be a big opal ring on her middle finger.

Although the Kansas City Chiefs star was unable to be present at the NYC night, when her sweetheart stepped out to party with besties Selena Gomez, Gigi Hadid, and more, fans believe that Travis has sent a very special gift to her.

Karly Bulinski, a Rare Carat gemologist, spoke to Page Six about the significance of the “very sentimental” stones he gifted to Swift.

The ring features opal, which is Travis Kelce’s birthstone, and blue topaz, which is Taylor Swift’s birthstone, which indicates the ring holds a “very sentimental” meaning to the couple.

Bulinski said that given its size and quality, she estimates the custom ring ranges from $10,000 to as much as $175,000.

The gem expert says the opal in Swift’s ring could be as large as 20 carats, putting the price of the custom piece in the range of $10,000.

But according to Mike Fried of The Diamond Pro, Swift’s new jewel could be worth much more. “The center stone on Taylor’s ring is massive and looks to be 15 carats. A high-quality opal of that size is incredibly rare, but not nearly as expensive as a diamond would be. I’d estimate it at around $175,000, if not more,” he tells Page Six.

He poignantly added, “Since ancient times, opals have symbolized good luck, fortune, and power — which seems to be particularly fitting for Taylor Swift.” Mike suggested the darker surrounding stones could be either tanzanite or blue zircon — both of which are also considered to be December birthstones. Tanzanite, he reportedly said, is “said to carry high energy and improve vitality.”

Opals have long been seen to symbolize transition, hope, and purity. This could be taken as a subtle hint about the couple’s blossoming romance.

There are rumors that Taylor and Travis will soon be engaged with rumors that Kelce has already asked her father before he decides to pop the question.

In the meantime, Swift will likely continue attending his football games this year as the Chiefs stopped their two-game losing streak with a win over the Patriots this past Sunday.

Swift has a 5-2 record when she shows up.
