Last week we had 3 five carat perfectly cut Hearts on Fire diamonds in our store. These diamonds were so special (and so expensive) that they had to be delivered by a Brinks armored truck! Talk about a gemologists dream come true. I was running around the store with my tweezers full of diamond talking to anyone that would listen to me about how rare it is to actually find a gem quality piece of rough big enough to fashion a 5-carat rock. Everyone, even the Fed-Ex guy, got a quick diamond lesson from me that day. And as I was gazing into the beautiful example of what our Earth can create over millions of years, I started thinking about some of the world famous diamonds that have been discovered over time. Here is the list I compiled of the 3 most expensive diamonds in the world.

1. The De Beers Centenary Diamond Weighing in at 273.85 carats this diamond is considered to be perfect in every way! No joke, it’s a D in color and flawless both inside and out – talk about a rarity. It was named the Centenary Diamond to mark the Centennial celebration of De Beers Consolidated Mines in 1988 when it was presented as an astonishing 599ct. piece of rough. It is valued at $100 million dollars and the people who were there for its discovery have been sworn to a life of secrecy. To learn more, click here.

 2. The Hope Diamond You can’t have a list of the most famous and expensive diamonds without this natural blue beauty making an appearance on the list. Weighing 45.52 carats this natural blue bombshell resides in the Smithsonian Museum in Washington D.C. (just one of the many reasons I want to visit that place!) and is estimated to be worth around $350 million! To learn more, click here.


3. The Cullinan Diamond Named after the mine it was discovered in, this amazing specimen of diamond weighed a whopping 3,106.75 carats or 1 1/3 pound when it was discovered in 1905 by Mr. Frederick Wells. This spectacular piece of rough produced 9 major gems, 96 smaller brilliants and 9.50 carats of unpolished pieces.  It is valued to be worth $400 million dollars. To learn more, click here.
