And here's my research on different legends and stories associated with the Orlov Diamond!
The Orlov Diamond started its journey in the Golconda mines in India and ended up in the scepter of the Russian Empress Catherine the Great.
It is now hosted in the Diamond Fund of the Moscow Kremlin in Russia!

Dear followers, most of your got it right!!! Congratulation!!

Sforza castle was taken as a prototype for the Moscow Kremlin!!
In fact Moscow Kremlin was built by the Italian architects - Aristotele Fioravanti, Petrus Antonius Solarius, Marcus Ruffus.

One of them - Aristotele Fioravanti – was working for Francesco Sforza and took part in the reconstruction of the Sforza castle in Milan, that took part in the XV century.

Aristotele Fioravanti was invited by the Russian Tsar Ivan III to reconstruct the Moscow Kremlin. The architect built the cental cathedral of the Kremlin - the Assumption Cathedral.

Fioravanti was also an experienced fortification engineer and it was him who created the plan of the walls and towers of the Moscow Kremlin.

Aristotele Fioravanti arrived to Russia in 1475, when he was 60 years of age and he spent the rest of his life there.
