The USP of this diamond is its beautiful yellow-brown colour with a bright reddish hue at the centre. It is the largest faceted diamond in the word.

The Golden Jubilee weighed in at a whopping 755.50 carats when it was discovered in South Africa's Premier mine in 1986.

Considering its large size, as well as the fact that it had deep cracks from the interior and several inclusions, it was cut in a specially built, underground, vibration free room. The stone was finally ready in 1990, after two years of work. It now weighed an impressive 545.65 carats.

This stunning diamond was gifted to Thailand's King Bhumibol Adulyadej by his country's businessmen. In honour of the occasion -- the 50^th anniversary of the King's ascent to the throne -- the diamond was named the Golden Jubilee.

The diamond is now on display in the Royal Museum at Pimammek Golden Temple Throne Hall in Bangkok.
