This weekend, former Apprentice star Luisa surprised fans by announcing she had got engaged to her millionaire boyfriend Andrew Collins.
Many of her followers were even unaware that Luisa was in a relationship, as businessman Andrew likes to keep out of the public eye.
However, the ring he surprised her in Paris with couldn't be anymore in ya face!
Declaring her happy news on Twitter, Luisa shared a picture of the hefty rock adoring her wedding finger, and experts have now given their opinion on the impressive piece of bling.
Lewis Malka, a fine jewellery expert, tells Reveal: "Luisa Zissman is one very lucky lady!
"Weighing in at a hefty eight carats, and at a very high spec colour and clarity, I would estimate this stunning ring to be worth £1.5million.
"The highlight for me is the split claws on the band, this maximises the light available to the diamond and shows off the incredible fire you would expect from a diamond of this standard. A beautiful piece of jewellery."
Blimey...careful you don't loose it, love!
