Most Expensive Diamonds ~ No. 5 ~ De Beers Centenary Diamond

The De Beers Centenary Diamond has a colour grade D, making it a diamond with the highest level of colour grading - colourless and flawless on the interior and exterior.    The De Beers Centenary Diamond is No. 5 on our list of most expensive diamonds, and worth a staggering $100 million dollars. The diamond has 273.85 carat and weighs 54.77 grams making it the third largest diamond ever discovered at the Premier Diamond mine.  It was introduced in May 1991 and was cut with an amazing 247 facets, giving it the scintillating look you see above. Colourless diamonds are rare - coveted because they reflect light from around them. It is named the Centenary Diamond as it was presented in the rough for the Centennial Celebration of De Beers Consolidated Mines on May 11, 1988. My Diamonds are currently showcasing their Christmas Collection.   Don't miss it!
