一顆淨度屬於IF（內部完美無瑕）嘅鑽石絕對係無價之寶——如果係一顆100卡嘅IF鑽石呢？
喺2015年4月，蘇富比拍賣行就以2千2百幾萬美元售出咗一顆100.2卡嘅鑽石。呢顆祖母綠切割嘅鑽石被形容是有如「一潭冰水般透明」。如此巨大而且完美無瑕嘅鑽石可以話係真正無出其右嘅存在。

What is the concept of a 100-carat diamond?
A diamond with the clarity rating of IF (Internally Flawless) is, without any doubt, a priceless treasure – what if it weighs 100 carats?
In April 2015, auction house Sotheby’s sold a diamond weighing 100.2 carats with the mind-blowing price of US$22.1million. The Emerald-cut diamond is described to be “as clear as a pool of icy water”. A diamond as flawless and enormous as this one is truly an unrivalled presence.
