The competition is now closed and the entries have been checked.
I can confirm that there were 419 Gummy Bears in the jar!
No-one guessed the exact amount, however, 4 people guessed within 1 Gummy bear, and so the prize of 1,500 diamonds will be divided between them.
Congratulations to DutchOrel and Jatu1979 with a guess of 418 and TyphiiSalmonella and redawk with a guess of 420.
Your prizes of 375 diamonds each have been awarded to your accounts.
