Diamond Size
A diamond is measured in carats. Carats are a measure of weight, each carat being equivalent to 200 milligrams. Carat weight roughly relates to size, as you can see below. We thought it may be useful to see the approximate size of different carat weights, but remember carat is really weight not size, the chart is only for illustrative purposes and is not exact . Learn more about carat size.
Diamond QualityThe quality of a diamond affects its price. A perfectly proportioned flawless clear stone will cost a great deal more than one with minor imperfections. In the Design-Your-Own section of our web site you can simply move a slider to alter the quality (and of course, the higher the quality, the higher the price). The Design-Your-Own wizard looks like this (right): The quality of a diamond is actually a complex thing involving how it was cut, what colour it is, and whether it has any defects. In our Design-Your-Own wizard, you can select an advanced view to see how all these things change as you alter the quality slider. In our Designer Range, our jewellery designer has pre-chosen the diamond, and the details about this are shown once you pick the ring you like. The price is, of course, shown too. |
