Taylor Swift has announced her engagement to her partner Travis Kelce, sharing a series of pictures, including one of the ring, on Instagram. The post was accompanied by the caption: Your English teacher and your gym teacher are getting married. Not every English teacher can afford a diamond ring costing six or even seven figures, however. Fans and curious onlookers have been sharing their opinions on the proposal and the eye-catching ring.

Kelce is reported to have designed the ring with a jeweller, with its vintage-inspired style seeming to match the aesthetic of Swift's newly announced album The Life of a Showgirl. Industry experts estimate it could cost anywhere from £500,000 up to £4 million, said Ruth Faulkner, the managing editor for Retail Jeweller magazine.

The diamond appeared to be an 8-10 carat vintage stone, which Ms Faulkner noted is quite rare for an antique piece, showing how celebrity engagement rings are moving towards grander styles. As seen with Zendaya and Dua Lipa, there is a marked shift towards unique designs and larger stones that defy traditional expectations.

Cristiano Ronaldo's partner, Georgina Rodríguez, also made news recently with a reported $5 million oval cut engagement ring, further fueling the trend of high-profile celebrity engagements. Buyers are also leaning towards lab-grown diamonds to cater to a wider variety of preferences and price points.

As couples explore options, the conversation around provenance, ethics, and personal stories behind engagement rings continues to evolve, promising an exciting future for those seeking love and unique adornments.
