One of the most useful tools a jeweller can have when designing jewellery is an idea of what different size rubies weigh.


The chart below is an easy way to reference what a ruby weighs in different sizes and shapes. This information together with other information in The Ruby Hub will then enable you to know more or less what carat size stone to look for and how that might affect your budget when costing a finished piece of jewellery.

A very useful tool in the jeweller’s tool box.

The weights for ruby sizes are approximate. Gemstones of all types are cut to maximise the look and life of the stone, so tend to be a little less standardised. This chart is essentially meant as a guide.
