Rare Diamond To Fetch Ksh 668 M Once Auctioned

The stone is one of the world's rarest diamonds.

According to Sotheby's Hong Kong deputy head of jewelers, Terry Chu, the diamond is known us "lady luck" because of the auspicious numbers that make up the size of the jewel.

“When a diamond is vivid yellow and over 20 or 30 carats size, it is very rare. This one is over 77 carats, Iwould say, it is the rarest diamond, among the rarest diamond in the world," said Chu

The number 7 is also considered auspicious in the Chinese culture because of its similar sound to the word "together" in mandarin.

The colour of the stone, yellow, is also considered lucky because it symbolizes royalty and wealth.

Also showcased were a pair of rare purple-pink diamond earrings expected to fetch up to 643 million shillings and a jadeite bead and diamond necklace also expected to fetch the same value.

Sotheby's Hong Kong magnificent jewels and jadeite spring sale will take place on April 6th, 2015.
