Vogue Williams and Spencer Matthews got engaged in February 2018 after announcing the news on Instagram with a photo of Vogue's incredible ring, and apparently it's worth a small fortune.
Speaking to the Irish Independent, diamond specialist Seamus Fahy of engagement ring specialists Voltaire Diamonds in Dublin, revealed that it is expected to have set Spencer back approximately £180,000.

Seamus explained: "The centre stone looks to be a 4ct centre radiant, with parallel baguette and trillion side diamonds making up a total carat weight of at least 1.25ct." He added that it would be "close to – if not over - €200,000".
When Spencer shared a picture of the ring on his own Instagram, he added that besides its eye-watering price tag, he also put a lot of thought into the jewel and designed it himself.

Vogue Williams' bespoke engagement ring
"My friend Neil @duttsonrocks and I really enjoyed the journey of making this beautiful ring for my fiancée @voguewilliams," he captioned the post. "I loved designing it and believe it suits her perfectly."
In fact, Spencer told HELLO! that the bespoke design was crafted to look like a bridge to reflect Vogue's love of architecture, while the Made In Chelsea star also had the date of the couple's engagement engraved on the inside.
He proposed live on stage after the couple enjoyed a performance of the Lion King. That also had sentimental value behind it.

"The engagement had to be special," Spencer explained. "And as our first trip away together was to Disneyland Paris, it felt like the perfect fit. The Lion King is also one of the greatest stories of all time, so I figured that having just had a romantic evening watching it, she'd probably say yes!"
Sure enough, just four months later, Spencer and Vogue tied the knot in June 2018 at Spencer's family's Glen Affric Estate in Scotland. They are now parents to son Theodore and daughter Gigi.
