The worlds largest Diamond called the Cullinan Diamond was named after the mine owner. Weighing at 3,106.75 carats. Discovered in 1905 in South Africa was to be presented and given to King Edward VII.
The issue was, how do you get such an expensive and precious stone to England without it being stolen or lost? What they did is that they held a large ceremony, where they loaded a lock box surrounded by London detectives onto a ship heading towards England. That was just a decoy to attract thieves, if they stole it they just stole a pretty stone of no value. The actual way they transported the largest and most expensive diamond discovered was just in a normal parcel that anyone could buy from the post office and sent it by post.
When the King wanted to cut the Diamond he entrusted it to the famous Asscher's Diamond Co. in Amsterdam. It took them 6 months of studying the Diamond before they even started to cut the it. When they were ready to cut the diamond the blade reportedly broke. On the second attempt, the Cullinan Diamond split in two as planned. A worker at the time said that Mr.Asscher fainted when he split the Diamond
