What name is given to the 86 carat gem housed in Istanbul's Topkapi Palace Museum?

Please, more clarity on the name. If a small stone already bears the name why refer to this one incorrectly? And why is any huge diamond called "Spoonmakers".

Why is it called the Spoonmaker’s diamond ? Are spoons so prized in Turkey that they are paid for in huge diamonds?

The shape is "Brilliant cut"

what a truly beautiful gem!!
