Diamond & Jewelry News, Advice and Prices for Consumers
September 9, 2010
I know girls love big diamonds, but I was very surprised to see in a store yesterday that a 1.5 carat diamond costs much more than two 1 carat diamonds! I mean one carat is also quite big and I can't believe that wearing two 1 carat diamonds (altogether 2 carats) is cheaper than owning one 1.5 carat stone. Can someone explains this mystery or did this jeweler loose his mind?

It's true that the bigger the diamond the more pricey it is, in a very steep curve, but you also have to be sure you are dealing with diamonds with the same qualities. Is it possible that in addition to being bigger, that 1.5 ct diamond has also better features than the two 1 ct diamonds? How are its color and clarity grades compares to the smaller diamonds? How good is its cut? These are all parameters you have to be aware of when you come to compare diamonds' prices.

This is quite common. If the big diamond was indeed exactly 1.5 ct, than it means it is in a different size range than the 1 ct diamond (1-1.49 is considered a certain size range, 1.5 is already a higher one). Even if the diamonds were all of the same size range then there's no doubt that the bigger one would cost much more than the other two. When it comes to diamonds, what matters most isn't the total size but the rarity. Finding two 1 ct diamonds is much easier than having one 1.5 ct one. Size equals rarity and rarity equals value, there's no way to avoid it. The diamond industry treats every diamond size range quite differently and you can bet that a 2 ct diamond would cost more than three 1.5 diamonds. The scale of value per size is by no means linear!
