An Infographic of Actual Diamond Size

Most Popular Diamond Sizes - Size Comparisons

Comparison of actual diamond sizes

Today we are going to look at the more popular sizes of diamonds. To do this, we are aiming to offer a size comparison between different sized stones. Keeping things nice and simple, we have photographed several popular sizes of diamond, typically chosen for engagement rings. We have also factored into this image, (not so useful to our overseas clients – sorry!) a British five pence piece purely for reference. This is the only time that we will relate the value of five pence with a diamond! The sizes below are references to the diameter of each diamond size. As the carat weight of each diamond increases, the physical size of the diamond will also increase. This infographic will be particularly applicable to the round diamond solitaire since varying fancy shapes of the diamond will exhibit varying dimensions to the round diamond illustrated.

What Makes a Diamond Size Most Popular?

The most popular diamond size includes the half carat diamond (0.50cts.) The reason for this is not only cost, but this diamond typically hits a budget that many people can realistically aspire to. When we focus on diamonds above one carat in weight, especially in higher colour and clarity grades, the cost rapidly escalates. With a half carat diamond engagement ring, it is possible to achieve a beautiful example set into 950 Platinum from around £1400 – £1500 (example based on G-H SI1-SI2 range) which exhibits a good clear purity grade with a good diamond colour, lacking any tint. For those wishing to further reduce the spend on such a ring, the 0.40cts size offers a significant step down in price, but a size difference that is hardly detectable by eye. As a result, 0.40cts round brilliant cut diamonds offer outstanding value for money.

 For those with a more substantial budget, the 0.70 – 0.80cts size is also a lovely choice. The diamond size contrasts greatly with the width of most engagement ring bands. Even those set with diamonds across the shoulders. This contrasting size, between band and diamond, provides aesthetic qualities, seldom achieved with much smaller diamond sizes which are closer in diameter to the width of the band (eg. a 2.5mm band with a 4mm diamond.) The larger diamond weights also allow the engagement ring setting to flare in a more pronounced way, from the base of the setting to the upper edges of the diamond.

The iconic size, has to be the aspirational 1ct diamond. There is something magical about a full one carat in weight. For those willing to sacrifice only a small few points from the overall weight, the dip below this magic weight will often reduce cost substantially.
