Wondering how big a 1-carat Oval Cut Diamond is or how much an 8x6mm Oval Cut Diamond weighs?
Then you have come to the right page as I have created a full chart and built a really easy-to-use calculator to help you get an idea of how much your Diamond weighs.
Quick Note: These are estimated weights only, the actual weight of your Diamond may be different depending on the proportions of the stone.
Oval Cut Diamond Weight Calculator
If you have the dimensions of your Diamond, you can use my free calculator below.
The calculator has been designed to automatically calculate the depth of the stone at 62% (which falls in the ideal range) but if you have this measurement, you can enter it in the box.
Oval Cut Size to Carat Chart
Images are for illustration purposes only as it is very difficult to accurately represent image sizes on screens.
Creating a chart for oval cut sizes is very difficult due to the incredible number of length-to-width combinations that there are, for example, there are numerous combinations for a 1-carat oval cut, such as:
But I have tried to include all of the popular calibrated sizes in the chart above and the calculator can be used if you have the length and width measurements of your Diamond.
And as with all size-to-weight charts, this should be used as a guide only as there are factors that impact the weight of an Oval Cut Diamond, including:
- Girdle thickness
- Length-to-width ratio
- Pavilion angle
- Whether the stone has wide shoulders
Another issue with doing weight estimation for Oval Cut Diamonds is that there aren’t any globally recognized ‘ideal’ proportions, which is why Oval Cut Diamonds aren’t given a cut grade by gem labs such as the GIA.
But I do hope that the chart and calculator are helpful in giving you and idea as to how much your Diamond might weigh.
