Where is the largest diamond in the world kept?

A portrait of Melania Trump with a 25-carat diamond on her left hand appeared on the official White House website. The first lady’s ring was given to her by her husband Donald Trump on their tenth wedding anniversary. Social media users were outraged, but if only they knew that 25 carats is not the limit. What the largest and most beautiful diamonds in the world look like – in the article “Gazeta.Ru”. The White House unveiled the first official portrait of Melania Trump. The president’s wife is dressed quite strictly: a black jacket from Dolce & Gabbana and a matching neckerchief. True, it is simply impossible not to notice the huge 25-carat diamond ring on Melania’s hand. It is not surprising that the portrait caused a lot of noise – the public immediately criticized the first lady for wanting to once again boast of her wealth. Users of social networks were confused by both the unfortunate pose and the overly retouched face of the president’s wife – in the photo, the 46-year-old ex-model looks suspiciously young, there is not a single wrinkle on her face. On the other hand, Melania’s diamond, although large, is still not the ultimate dream.
