Wondering how big a 1-carat Pear Cut Diamond is or how much an 8x6mm Pear 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.
Pear 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 60% (which falls in the ideal range) but if you have this measurement, you can enter it in the box.
Pear Cut Size to Carat Chart
0.5 Carat = 6.6 x 4.6mm
0.75 Carats = 7.3 x 5.4mm
1 Carat = 7.7 x 6.0mm
2 Carat = 9.6 x 7.6mm
3 Carat = 10.8 x 8.8mm
Images are for illustration purposes only as it is very difficult to accurately represent image sizes on screens.

Creating a chart for Pear Cut sizes is very difficult due to the different number of length-to-width combinations, which can range from below 1:25 to more than 1:50, for example, there are numerous combinations for a 1-carat Pear Cut, such as:
- 7.2×6.2mm
- 8.6×5.7mm
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 Pear Cut Diamond, including:
- Girdle thickness
- Length-to-width ratio
- Pavilion angle
- Whether the stone has wide shoulders
Another issue with doing weight estimation for Pear Cut Diamonds is that there aren’t any globally recognized ‘ideal’ proportions, which is why Pear 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.
