Which colored diamonds are the most expensive?

The most expensive colored diamonds are the ones that are the rarest. The rarest colored diamonds include red diamonds (rarest of them all with less than 20 natural red diamonds in existence today), pink, green and blue diamonds. Of course, there are three other factors that together with color determine the price of a given diamond, namely cut, clarity and carat, but throughout this article I will mainly focus on color.

The largest price paid for diamond was $9.49 million, for a pink diamond weighing 7.03 carats. Australia is the origin for the majority of the world’s pink and red diamonds. Pink and red natural diamonds are so rare that only a handful of jewelers actually have the chance to look at these wonderful stones.

Famous red diamond Moussaieff Red, weighing 5.11 carats achieved the incredible price of $8 million, more than $1.5 million per carat. Another very expensive red diamond was Hancock Red, weighing just 0.95 carats but was still achieving a huge price of $880,000 in 1987.

Natural blue diamonds are also very expensive - fancy vivid blue diamond weighing 6.04 carats achieved $7.9 million, at the auction in Hong Kong in October 2007. In average, blue diamond engagement rings cost in average 10 to 50 times more than white diamond engagement rings.

Other colored diamonds can also achieve huge prices, vivid yellow diamonds, for instance, can cost more than $50.000 per carat. Vivid orange diamonds also achieve huge prices – for instance 8.93 carat Fancy Intense Orange diamond achieved $1.9 million at Sotheby, while 5.54 carat Pumpkin Diamond achieved the price of $1.3 million.

The thing that you also need to know is that these high astronomical prices refer only to diamonds created in nature, meaning that colored diamonds produced in lab have significantly smaller price tags.
