Comparing the Sizes of Princess Cut Diamonds

A photographic comparison of popular Princess cut diamond sizes.

A comparison of sizes for the Princess cut diamond - photos of actual sizesDiamond sizes are not the easiest things to visualise. Few jewellers will have a specific loose or mounted diamond, available to view across all sizes. Differentiating between the many sizes is therefore extremely difficult. We can all look at tabulated information on diamond sizes, until the cows come home, but without a further grasp of how each size compares.

Today, I’ve decided to set out to a few Princess cut diamonds, from stock parcels, to show how each size relates to the next size, with a little more information on each size.

We begin with the 1 carat diamond  which typically for a Princess cut measures 5.5mm across the stone. Of course many other sizes exist, depending on the make of the stone – how thickly the diamond has been cut, and sizes vary for in-between diamond weights. Princess cuts can also be cut in less square shapes. For the sake of reference we have selected diamonds that are closer to a 1 : 1 ratio. Such proportions lend themselves far better to standard engagement ring settings.

The size that we find most popular tends to be the 0.50cts size (4.5mm) for both cost and appearance. The final size we have gone down to, is the 0.25cts diamond. Some of our mounts accommodate this size, but more typically we begin at 0.30cts for Princess cuts. (This size, owing to its closeness to 0.40cts has been ommitted.)

A further photographic reference can be found on our information page showing some actual photos of Princess cut engagement rings.
